[orca-list] Please test Orca master with Firefox

[Joanmarie Diggs <jdiggs igalia com>]

Hey all.

The issue that Alex and Nolan reported was a side effect of my trying to 
work around the broken-offscreen-text issue. This issue, for those of 
you who are not familiar with it, goes something like this: Authors 
think the best way to make their site accessible is to position some 
text offscreen so that sighted users won't find it but it will show up 
in the accessibility tree where screen readers will find it. 
Unfortunately, this "fix" often results in our being given the text one 
character or one word at a time when we ask for a line of text. 
<snark>Thanks authors and browsers!</snark>.

Anyhoo, in addition to the fix I committed for the problem that Alex and 
Nolan reported today, I just committed a totally different heuristic 
workaround for the off-screen text issue. One possible side effect is 
that if an author deliberately writes non-editable text that is one word 
per line for the entire text, Orca's going to ignore that authoring and 
pretend it's a single line. I'm not sure if that should be considered an 
Orca bug or an Orca feature. ;) I do not *think* there will be other 
side effects, but I've been wrong before. And we're getting awfully 
close to code freeze.

Long way of saying what's in the subject: If you are able to test Orca 
master with Firefox, please pull now and begin doing so.

Thanks in advance. Y'all rock!
