1224339 - Handle asynchrony between accessible and DOM trees when a11y check is enabled in marionette.

Status: RESOLVED FIXED

(Remote Protocol :: Marionette, defect)

Description

[Yura Zenevich [:yzen] (please use "needinfo")]

Right now we only make one attempt to retrieve and accessible object for an element. This is problematic because accessible tree and DOM tree might be out of sync for a short little while (while a11y tree is updating). Thus we need to attempt to retrieve and accessible object several times. We already had that approach in Gaia Python tests (https://github.com/mozilla-b2g/gaia/blob/master/tests/atoms/accessibility.js#L16-L36) but it should be universal and available to all clients.
