Not clear what caused this. Looks like an intermittent error because last time I saw this a retry would work.

#12592

[izgzhen]

@Ms2ger What is the connection between them o_O? I mean, #12592 only talks about /html/semantics/embedded-content/the-iframe-element/iframe-allowfullscreen.html

[Ms2ger]

The only error in your summary is

{"status": "CRASH", "line": 190394, "subtest": null, "action": "test_result", "test": "/html/semantics/embedded-content/the-iframe-element/iframe-allowfullscreen.html", "message": null, "stack": null, "expected": "OK"}

You're not really expected to read that, though; the human readable log has

I don't know what the output in the errorsummary means, but the test that actually failed was the one reported in #12592.

[izgzhen]

Oh I see. the summrarylog is a bit messy. Thanks :)
