In test_gamepad_connect_events.html, we should replace test_check_timestamp_iframe.html with test_connect_events_iframe.html, it should be the original purpose. It seems to be a typo at Bug 1347482.
I tried to correct it with test_connect_events_iframe.html, but it occurs some timed out issues. Lenzak, could you take a loot at this?
There are intermittent gamepad mochitest failure about test timeout described in bug 1296102 around for quite a long time, but they all only happen on Windows, I suspect the timeout you encountered is caused by other regression.
