I am not sure what the rules for focus are nowadays and if that event is really supposed to fire synchronously. If not, I guess we want to delay calling finishJSTest() until the focus event has fired. Alternatively, we could mark div1 as display:none. 1808918 4 442503 cdumez 2021-10-26 10:13:24 -0700 Created attachment 442503 Patch 1809349 5 ews-feeder 2021-10-27 11:30:36 -0700 Committed r284933 (243603@main): <https://commits.webkit.org/243603@main> All reviewed patches have been landed.
