1864240 - Investigate if widget-overflow panel in Synced Tabs Menu in Customizable UI needs to be updated to pass a11y_checks

Status: NEW

(Firefox :: Settings UI, task, P3)

Description

[Anna Yeddi [:ayeddi]]

There is a failing test in the browser/components/customizableui/test/browser_synced_tabs_menu.js that appear to, in some environments, send a click event on a panel button while the panel itself is still in the showing state.

We should wait for the panel to be shown to keep the test harness happy and to ensure the test is proceeding as it is expected to. Similar behavior was unpacked during the investigation of the bug 1859035 and bug 1863815.

Update: so far I was not able to confirm that the panel is not yet shown (i.e. try run with the log output that the panel is open), so this issue needs further investigation.
