[orca-list] orca doesn't recognize changed button texts in firefox

[Halim Sahin <halim sahin t-online de>]

Hi,
I've updated to debian  testing  which uses orca 3.14.

I couldn't find a working solution for the following problem:
On websites which change the text of buttons, orca rdoesnt update the 
displayed text.
<button typoe="button" ....> some text </button>
Now use javascript and change the text between the <button> </button>
Orca doesn't update the content.
Tested it with nvda and jaws.
Nvda updates the displayed text very reliable. Jaws need tabbing away 
and back to the button to display new text.

Hints?
