[orca-list] Call for testing master with web content

[Joanmarie Diggs <jdiggs igalia com>]

Hey all.

The problem reported by Hypra regarding Orca presenting and navigating
in etherpad when that page tab was not focused happens to be due to a
bug in either etherpad and/or Firefox. We're getting events that suggest
you're in that pad even though you're not. To make matters more fun,
checking the state of the non-focused document results in our being told
that it's focused.

Soooo.... I've added a couple of hacks designed to filter out those
events. There's a chance the filter might be too enthusiastic which will
cause Orca to stop presenting things it should (and used to) present.
I've decided to risk it even though we're getting quite close to the end
of this release cycle on the grounds that fixing this issue would be
good. I would ask you all to test master thoroughly with web content
starting.... NOW! :)

If you find any issues, please verify they are regressions first. To do
so, locally revert the following:

=====
commit 21aff9d5fb6252ee44f2a29f96f1018e84576426
Author: Joanmarie Diggs <jdiggs igalia com>
Date:   Fri Feb 8 12:01:32 2019 -0500

    Attempt to identify and ignore bogus events from background etherpad
=====

If that magically fixes things, then yup, it's a regression and I need
to know about it ASAP.

Lastly, please direct questions about git to the mailing list. Many
users here can help you. And I have more things I'd like to accomplish
prior to code freeze.

As always, thanks in advance!!
