<h3>Log Message</h3>
<pre>Merge <a href="http://trac.webkit.org/projects/webkit/changeset/186393">r186393</a> - Crash when setting text direction via MakeTextWritingDirection* editing commands.
<https://webkit.org/b/146665>
<rdar://problem/20835477>
Reviewed by Ryosuke Niwa.
Source/WebCore:
Fix two buggy clients of enclosingBlock(node) that would fail if the returned
element is the same as the node passed in.
Test: editing/style/change-text-direction-crash.html
* editing/ApplyStyleCommand.cpp:
(WebCore::ApplyStyleCommand::splitAncestorsWithUnicodeBidi):
(WebCore::ApplyStyleCommand::removeEmbeddingUpToEnclosingBlock):
LayoutTests:
Add a test that covers some very simple MakeTextWritingDirection* command usage.
* editing/style/change-text-direction-crash-expected.txt: Added.
* editing/style/change-text-direction-crash.html: Added.</pre>
