[orca-list] List item counts sometimes spoken when list item preference is turned off

[Kyle <kyle4jesus gmail com>]

I can think of two examples where two or three 100% reproduceable 
examples where I hear list item counts spoken by Orca, even though 
"announce list information during navigation" on the speech page is 
turned off. First, I hear it both in the "To/CC/BCC fields and in the 
attachment list in Thunderbird. It speaks "Multi-select list with x 
items" in both places, and the To, CC and BCC fields always present 3 
items, even if there is only one recipient. I'm not sure why it's saying 
this, but I thought I wasn't supposed to hear any item count there, 
especially not an erroneous count, even if the list information 
preference is turned on, since I didn't think this was supposed to be 
presented as a list. The other place I always hear item counts is in the 
device list in the Blueberry bluetooth management application. Again, 
the count is erroneous, though it seems to vary from time to time. This 
is announced as "Device list with x items," but the number is never the 
same and is usually incorrect, and again, the list information setting 
is turned off. If it helps, I can report this on the GNOME Gitlab to 
make it easier to track, but I figured it would be good to report it 
here, since more people can confirm it on the list. Thanks for any help 
with this issue.
