I attached a test script that shows an entry. The script reacts with a11y events, pointing the mouse where a change is detected in entries.

the base label that the scripts creates works, but the bug appears in mate's suite's labels, like the launch menu (alt-F2) or mate-search-tool. Is it because they are using custom widgets?

Anyway i'll try and get someone from mate to have a look too. please indicate me if it's up to them to fix it, i'll forward the bug.
