Move mouse pointer onto another bookmark AR: The tooltip keep staying, still appeared, not disappeared, until mouse pointer moved out the bookmarks tree area or moved on to the tooltip. ER: The tooltip disappears and a new tooltip for the bookmark under the mouse pointer appears. mozregression: 9:08.54 INFO: Last good revision: bf20544a7385ff761ba0da45fb4996153d88025f 9:08.54 INFO: First bad revision: 12ae47283fc97ccfe5af32d6e6cca88e44ae901a 9:08.54 INFO: Pushlog: https://hg.mozilla.org/integration/mozilla-inbound/pushloghtml?fromchange=bf20544a7385ff761ba0da45fb4996153d88025f&tochange=12ae47283fc97ccfe5af32d6e6cca88e44ae901a 9:09.65 INFO: Looks like the following bug has the changes which introduced the regression: https://bugzilla.mozilla.org/show_bug.cgi?id=1332812
Specifically, this regressed with https://hg.mozilla.org/integration/mozilla-inbound/rev/d4cafa51586a
This change in nsXULTooltipListener::GetSourceTreeBoxObject is clearly wrong: - nsCOMPtr<nsIDOMXULElement> xulEl(do_QueryInterface(sourceNode->GetParent())); + RefPtr<nsXULElement> xulEl = nsXULElement::FromContent(sourceNode); and fixing that makes the problem go away.
