Bug 1391756 - Try to fix rare timeout in dom/tests/mochitest/fetch/test_readableStreams.html. r?baku

Details | Review
24 failures in the last 4.5 days: https://brasstacks.mozilla.com/orangefactor/?display=Bug&bugid=1391756 android and windows 10 are the primary failure patterns, I think the increase is android. :gbrown, sorry to keep adding things to your list- this seems to fall into a pattern like many of the other android failures- is this something you could add to your general list of android failures and maybe a root cause will be obvious?

I don't see an obvious connection to other current Android issues. This is a new-ish test added in bug 1128959. :bkelly/:baku -- Can you have a look / see if you can make this test more reliable?

Jet, here's another potentially-related-to-Stylo intermittent failure.

Stylo is not yet enabled for Android.

This very rare timeout should not block streams from shipping.

There are four occurrences that still have logs available. In all four, this happens after: > JavaScript error: http://mochi.test:8888/tests/dom/tests/mochitest/fetch/common_readableStreams.js, line 26: TypeError: iframe.runTest is undefined; can't access its "call" property I see two possibilities here. 1. The iframe races with the tests. If the tests reach this line of code before the iframe is finished loading, we get this error. Usually the iframe wins the race and we're fine. 2. Something is actually causing the iframe to fail to load.
Also removes an infinite regress of nested iframes. The original problem was that tests would start running before the child iframe was done loading. The straightforward fix is to have the child frame start the test. But this caused further error messages because the child iframe is loaded more than once; removing the iframe from the iframe fixes this.
