With the fix for Bug 208875, all of the tests in the directories: webgl/2.0.0/conformance2/textures/canvas/ webgl/2.0.0/conformance2/textures/image_data/ now pass, and should be rebaselined with expected pass results, and enabled.
The webgl_canvas/ tests will all pass after the fix for Bug 183151 and should be re-enabled at the same time.
The webgl_canvas/ tests require additional bug fixes. Splitting off their enabling into a separate bug.
