Created attachment 409431 [details] Screenshot from STP 113 debugger of Gamepad object Reproduces on Safari 14.0 GA on iPad and iPhone. There may be other ways of triggering this, but one that often works is killing the browser from a page that is polling the gamepad. When reopening that page, getGamepads continues reporting a gamepad attached, but the .id and .mapping fields of the Gamepad are now set to "", which confuses the page. See attached debugger screenshot for details. Previously for this controller .id was reported as "Kishi Extended Gamepad" and .mapping was "standard".

Any updates on this issue? It's pretty common in my use of Safari 14.

This no longer reproduces (though I'm not sure when it was resolved)
