WebGL video tests display the initial startup message but do not execute any tests on Android when running on top of ANGLE and the passthrough command decoder.  No error messages are printed to the log.

This is only reproduceable sometimes on a local device, unclear if it's per-build or per run of the browser.  The test either runs quickly or not at all.

Affected tests:
conformance/extensions/oes-texture-float-with-video
conformance/extensions/oes-texture-half-float-with-video
conformance/textures/image_bitmap_from_video/*
conformance/textures/misc/tex-video-using-tex-unit-non-zero
