Comment 1

[Boris Chiou [:boris]]

test6() is pretty unstable and it makes the whole test file timeout. The test framework of ResizeObserver should continue to check the following tests even if there is a timeout (because we use window.setTimeout to check this case). However, test6() may wait for a message from an iframe forever. So I think we should split it from observe.html and then make it an intermittent.

[Boris Chiou [:boris]]

Attachment: Bug 1725051 - Reduce the side effect of iframe test in observe.html.

test6() has side effects because it is waiting for a message from the
iframe. If it doesn't get anything, the whole test file is timeout and we
don't continue to test other subtests. I'm trying to remove this side
effects of the subtests to avoid unclear intermittent error messages.
Besides, we resolve the promise earlier so hope it helps.
