Changed paths:

M Tools/TestWebKitAPI/Tests/WebCore/HTMLParserIdioms.cpp
Log Message:
-----------
Allow underscore in attribute names in the HTML fast path parser
https://bugs.webkit.org/show_bug.cgi?id=310961
Reviewed by Anne van Kesteren.
isValidAttributeNameChar() only accepted alphanumeric characters and '-',
rejecting '_' which is valid per the HTML spec. This caused unnecessary
fallback to the slow parser for attributes like data_value="...".
