Please file bugs on http://bugs.webkit.org/ for each individual issue, even if
you're not sure it's a bug.

Reduced test cases for each bug (that fail on Safari/WebKit but work on MSIE or
Firefox) would help a lot!  Please attach the test cases as HTML files rather
than pasting the HTML in a comment.
