Reviewed by Ryosuke Niwa and Daniel Bates.
Source/WebCore:
We would not notify the parent when text node content changed in a shadow tree.
Test: fast/shadow-dom/shadow-style-text-mutation.html
* dom/AuthorStyleSheets.cpp:
(WebCore::AuthorStyleSheets::updateActiveStyleSheets):
Invalidate shadow root children instead of the root itself when doing full invalidation.
The invalidity bits have no meaning for non-element, non-texts.
* dom/CharacterData.cpp:
(WebCore::CharacterData::parserAppendData):
(WebCore::CharacterData::setDataAndUpdate):
(WebCore::CharacterData::notifyParentAfterChange):
Add a helper and call it also in shadow trees.
(WebCore::CharacterData::dispatchModifiedEvent):
* dom/CharacterData.h:
LayoutTests:
* fast/shadow-dom/shadow-style-text-mutation-expected.html: Added.
* fast/shadow-dom/shadow-style-text-mutation.html: Added.
