I'm inclined to roll out this patch because this may actually be a real problem with the code. Will try to contact the author or reviewer on IRC first.

[Kenneth Russell]

Pinged tonikitoo on IRC about this but wasn't able to reach carewolf. I'm rolling out this patch because of potentially real problems in the code -- suppressing the assertion failure in TestExpectations seems like a bad idea.

[Kenneth Russell]

Reverted r126026 for reason:

Caused assertion failure in layout test touchadjustment/context-menu.html

Committed r126069: <http://trac.webkit.org/changeset/126069>

[Allan Sandfeld Jensen]

The assertion is wrong, and the case asserted was actually handled in the final patch. I will remove the wrong assertion in a new version of the patch.
