fast/images/animated-gif-iframe-webkit-transform.html is flaky

[Alexey Proskuryakov]

fast/images/animated-gif-iframe-webkit-transform.html is flaky - mostly on debug bots, but also on release sometimes.

-PASS isFirstImagePaused() is false
+FAIL isFirstImagePaused() should be false. Was true.

This is a fairly new test. Chris, do you know what could be wrong here?

I couldn't reproduce locally, even with many parallel processes.

I wrote this test. I'll take a look tomorrow.

Like other gif animations test relying on internals.hasPausedImageAnimations(), it doesn't work (reliably) on WK1. We already have a section in wk1 TestsExpectations to skip those.

However, on WK2 it should work so I'll have to investigate. My initial feeling is that we'll like need to use shouldBecomeEqual() for isFirstImagePaused(), like we already do for isSecondImagePaused().
