Spun off bug 1256706. Twitter used to do a CSS change from position:absolute; to position:relative; when focus changed from one tweet to the next, see bug 1256706 comment #4 and dholbert's analysis in bug 1256706 comment #5. Implement a solution on the accessibility APIs side as suggested in bug 1256706 comment #7: > Also we could try to make the accessible tree updates smarter, like if a > frame type of a DOM node wasn't changed during frames reconstruction then no > accessible update should be required. This check shouldn't be very expensive. Alex, you also said you had a prototype working. Could you finish this on this bug?
