Description Aakash Jain 2020-02-17 12:24:31 PST 
Regression: fast/hidpi/image-srcset-svg-canvas.html is extremely flaky on iOS EWS.

This test was passing earlier on iOS, since around Feb 7, it started being extremely flaky on iOS EWS. This was probably just after another test (fast/hidpi/image-srcset-svg-canvas-2x.html) was marked as failing in https://trac.webkit.org/changeset/255985/webkit

Changed expectations to force a skip of compositing/webgl/webgl-reflection.html on EWS instead of the two test fast/hidpi/image-srcset-relative-svg-canvas-2x.html and fast/hidpi/image-srcset-svg-canvas-2x.html.

I don't see any reason to track this separately from bug 207038, it's clearly the same cause.
