Re: [orca-list] Another page where caret navigation is stuck

[Joanmarie Diggs <jdiggs igalia com>]

Hi Peter.

I have good news and bad news. The good news is that the specific bug
you reported here is fixed. The bad news is that there are other places
on that same site (including a set of elements shortly after the
elements of your report) where there is some looping.

The problem is that the site is using a:focus{position:relative;} and as
a result, giving focus and/or setting the caret into those objects
causes Gecko to destroy the element you just navigated to and create a
new one in its place. The proverbial rug is literally being pulled out
from under you. Why? Couldn't tell you. I put some defensive logic in
place which handles the case of your report along with another bug that
was on my to-do list. But that logic is insufficient so far to handle
all the cases. If you're curious, pull the latest master, arrow Down a
bunch in that site and then grep in your full debug.out for ZOMBIE and
HACK. Or just read the accessible events. You Down Arrow and suddenly
Gecko gives us children-changed and text-changed events for the
destruction and re-creation of your location.

Ultimately I'll see about putting in some more defenses. But I feel like
it would be a better use of my time to try to improve support for more
frequently-used sites and web apps who are not destroying children by
design. <tired smile>

Sorry I don't have it all resolved yet.
