Hello,
web content line by line using down arrow key in browse mode.
Sometimes 
it gets stuck and it is not possible to move past a certain point, 
sometimes it jumps to the top of the page instead. Also interesting
is 
the fact this is only happening while navigating forward (pressing
down 
arrow key). When navigating backward it's not happening for me.
Very often it's the embedded youtube frame that can be used to
reriably 
reproduce the problem.
Here are my steps:
* Load this article in firefox with orca running. 
https://matrix.org/blog/2021/06/18/this-week-in-matrix-2021-06-18
* From the top of the page navigate to the first heading at level 2 
saying "Matrix Live 🎙"
* From there use quick navigation to move to the next link (that's
the 
youtube channel picture photo).
* Now navigate forward line by line until you can reproduce the
issue.

Expected results:
Orca should navigate line by line allowing to read the whole article 
including embedded content.

Actual results:
top or is stuck on a particular spot of a web page.

Notes
I've used some trial and error and found the commit ac37d8c59 that 
introduces this behaviour.
Looking at the commit description I can see and speculate a bit that
it 
might be happening when there are some non live region content inside
a 
live region.
Another place where this is frequently happening but I can't
reproduce 
matrix client. There is a similar concept in their message timeline.
The 
whole timeline is a live region with aria-level set to polite and
each 
message has a toolbar of buttons. This toolbar has aria-live=off and 
that's again the spot where it breaks. This time orca is often
getting 
stuck for me.

Can you please take a look?

Greetings

Peter
