Changing URL to sample HTML that minimally demonstrates the leak and to form handling code since it seems to only happen so far in display of select menus for forms.

I'm arbitrarily declaring M8 my UMR/MLK milestone. :)

I still haven't got Purify working on Solaris, and won't receive Purify for NT for a few weeks. Marking these M10

After careful consideration, I've decided that I probably won't get this bug in for M12. Currently I have nearly 50 bugs scheduled for M13, so there is a possibility that this bug may need to be moved out farther still.

QA Contact update.

Triaged to M14

adding top100 keyword.

Moving off to M16 - please speak up of you need this for M14, thanks!

Rescheduling (*sigh*) Some of these are from M4. I wonder if they are all still valid?

We are no longer leaking StyleContextImpl's. In fact, I just did a walk of about half of the top100 (Chofmann's browser buster test). We leaked 5 webshells and just over 1Mb of other stuff, but no StyleContextImpl's!

Updating QA contact.
