It seems to be a bug in the test, it's not signaling completion. I'll fix the test, sorry about my carelessness!

The test is now fixed on WebGL master branch, so the bug will be fixed by the next WebGL roll.

Has been fixed for a while, checked that the test expectations look correct in latest source.

Cleaning up WebGL test failure expectations.

Many of these are leftover failure expectations from fixed bugs.
Some were fixed on some platforms but not others. There are some
new failures that were hidden by previous broad suppressions. Also
some tests are only failing because we haven't updated the drivers
on the bots (http://crbug.com/887241).
