    Trix supports all evergreen, self-updating desktop and mobile browsers.
    
 
 Trix is built with emerging web standards, notably [Custom Elements](http://www.w3.org/TR/custom-elements/), [Mutation Observer](https://dom.spec.whatwg.org/#mutation-observers), and [Promises](https://people.mozilla.org/~jorendorff/es6-draft.html#sec-promise-objects). Eventually we expect all browsers to implement these standards. In the meantime, Trix includes [polyfills](https://en.wikipedia.org/wiki/Polyfill) for missing functionality.

Subject: [PATCH 185/938] Toolbar buttons are removed from the navigation flow

Every toolbar button gets a tabindex property with a value of -1. It removes the buttons
from the navigation flow, meaning a user cannot tab to it. It improves usability when
Trix is placed after a focusable field (i.e. the user can tab directly to the content
area). It also improves the accessibility of Trix.

Subject: [PATCH 186/938] Fix 'Invalid property value' for trix toolbar default
 CSS

Chrome tells me that 'collapse' is not a valid property for 'white-space'. Based on trix.css, I think it should be 'nowrap'?

Subject: [PATCH 195/938] Downgrade selenium-webdriver to avoid flaky iOS tests

Hi Javan!

Based on the error message, this appears to be the issue  that i've seen here and there where if the code is using the Java Selenium 3.x bindings, Appium has issues parsing the capabilities and it produces the error that you see.

If you downgrade your bindings to 2.53.1 or use the 3.2.0 bindings, do you see any improvements?

Best,
Chip Vaughn
Customer Support Engineer

     element, for example), we need a slightly complicated approach to get the boundary's offset in
-                        IE. The facts:
-
-                        - Each line break is represented as \r in the text node's data/nodeValue properties
-                        - Each line break is represented as \r\n in the TextRange's 'text' property
-                        - The 'text' property of the TextRange does not contain trailing line breaks
-
-                        To get round the problem presented by the final fact above, we can use the fact that TextRange's
-                        moveStart() and moveEnd() methods return the actual number of characters moved, which is not
-                        necessarily the same as the number of characters it was instructed to move. The simplest approach is
-                        to use this to store the characters moved when moving both the start and end of the range to the
-                        start of the document body and subtracting the start offset from the end offset (the
-                        "move-negative-gazillion" method). However, this is extremely slow when the document is large and
-                        the range is near the end of it. Clearly doing the mirror image (i.e. moving the range boundaries to
-                        the end of the document) has the same problem.
-
-                        Another approach that works is to use moveStart() to move the start boundary of the range up to the
-                        end boundary one character at a time and incrementing a counter with the value returned by the
-                        moveStart() call. However, the check for whether the start boundary has reached the end boundary is
-                        expensive, so this method is slow (although unlike "move-negative-gazillion" is largely unaffected
-                        by the location of the range within the document).
-
-                        The approach used below is a hybrid of the two methods above. It uses the fact that a string
-                        containing the TextRange's 'text' property with each \r\n converted to a single \r character cannot
-                        be longer than the text of the TextRange, so the start of the range is moved that length initially
-                        and then a character at a time to make up for any trailing line breaks not contained in the 'text'
-                        property. This has good performance in most situations compared to the previous two methods.

+                          For the particular case of a boundary within a text node containing rendered line breaks (within a
+                          
     element, for example), we need a slightly complicated approach to get the boundary's offset in
+                          IE. The facts:
+
+                          - Each line break is represented as \r in the text node's data/nodeValue properties
+                          - Each line break is represented as \r\n in the TextRange's 'text' property
+                          - The 'text' property of the TextRange does not contain trailing line breaks
+
+                          To get round the problem presented by the final fact above, we can use the fact that TextRange's
+                          moveStart() and moveEnd() methods return the actual number of characters moved, which is not
+                          necessarily the same as the number of characters it was instructed to move. The simplest approach is
+                          to use this to store the characters moved when moving both the start and end of the range to the
+                          start of the document body and subtracting the start offset from the end offset (the
+                          "move-negative-gazillion" method). However, this is extremely slow when the document is large and
+                          the range is near the end of it. Clearly doing the mirror image (i.e. moving the range boundaries to
+                          the end of the document) has the same problem.
+
+                          Another approach that works is to use moveStart() to move the start boundary of the range up to the
+                          end boundary one character at a time and incrementing a counter with the value returned by the
+                          moveStart() call. However, the check for whether the start boundary has reached the end boundary is
+                          expensive, so this method is slow (although unlike "move-negative-gazillion" is largely unaffected
+                          by the location of the range within the document).
+
+                          The approach used below is a hybrid of the two methods above. It uses the fact that a string
+                          containing the TextRange's 'text' property with each \r\n converted to a single \r character cannot
+                          be longer than the text of the TextRange, so the start of the range is moved that length initially
+                          and then a character at a time to make up for any trailing line breaks not contained in the 'text'
+                          property. This has good performance in most situations compared to the previous two methods.
