Random failure/crash in gpu_tests.webgl_conformance_integration_test.WebGLConformanceIntegrationTest.WebglConformance_conformance_extensions_oes_texture_float_with_image

Project Member Reported by brat...@opera.com, Dec 28 2017 
For tracking,  gpu_tests.webgl_conformance_integration_test.WebGLConformanceIntegrationTest.WebglConformance_conformance_extensions_oes_texture_float_with_image failed in https://ci.chromium.org/buildbot/tryserver.chromium.mac/mac_chromium_rel_ng/618826 and I've not seen it fail normally.

If I read the log correctly (lightly edited below), this is a timeout most likely caused by a tab crashing.

Thanks for reporting. The test and the bulk of its sources are here:

https://cs.chromium.org/chromium/src/third_party/webgl/src/sdk/tests/conformance/extensions/oes-texture-float-with-image.html
https://cs.chromium.org/chromium/src/third_party/webgl/src/sdk/tests/js/tests/tex-image-and-sub-image-2d-with-image.js

Looking through the source code I don't see any obvious race conditions like setting the onload handler after setting the src of an image. There's probably a bug somewhere like Image elements' onload handlers not getting called because the image was GC'd (this has happened in the past). We should see if we can add more logging to this test that shows up in the bots' output so that we can diagnose bugs like this from the logs.

Just triaged this in  Issue 797368 . It's surely the same problem so duplicating this into the other bug.
