With keyboard APZ we do a lot of work to ensure that changes to the keyboard scrolling target happen synchronously with respect to key scrolling. Currently we disable keyboard APZ for a bunch of common situations. Bug 1383900, bug 1385071, and bug 1376551 are looking to improve this situation I think it'd be interesting to have data on how frequently a "race" would occur if we allowed asynchronous keyboard scrolling and changes to the focus of the page. If this is nonexistent then this behavior may not be relied upon much. I think this probe is possible with the information we have in keyboard APZ. I need to think some more on the exact metric we'd be measuring.
