Thanks for your review!
I've landed the patch as http://trac.webkit.org/changeset/71618 with modifying WebKit/chromium/ChangeLog as it had double ChangeLog entries.
BTW, this broke PopupMenuTest (which lives upstream), though only the Windows build (it doesn't get built for other platforms). Should be fixed with http://trac.webkit.org/changeset/71631.
Oops. I thought I git-grepped with the symbol but I somehow missed it. Thanks for fixing this!
Looks like this was landed.
