This is not a bug, it's a feature request: would it be possible to implement searching inside text areas? It would be useful. Thank you.
This is already in Radar as <rdar://problem/3099526>. That bug requests searching in form text fields as well as textareas. This should become significantly more straightforward to implement when textareas no longer use NSView for their implementation.

This still doesn't work even after moving away from NSView (unless I missed something and the new resizable text areas are still using NSView). This is a big usability issue for web apps that allow editing but don't use WYSIWYG editors (which seem to be a workaround for this bug).

Fixed in <http://trac.webkit.org/changeset/34822>.
I should mention that the fix for this seems to have caused a regression...
