There might be a bug somewhere in the Orca code.  You might try two
things to determine more about what your application is emitting for
events:

1) Run accerciser and monitor all the events from Firefox to see what
happens when you perform the user action above.

2) Enable full debugging in Orca (http://live.gnome.org/Orca/Debugging)
and see what events it is getting when you perform the user action
above.

If appropriate events are being delivered, we can take a look in Orca to
see why it isn't presenting the region.
