Message : Fix EGLContextCompatibilityTest. The check for "IsPlatformAvailable" was inverted. We were incorrectly trying only to create a context on invalid configs. Bug: angleproject:4449 Change-Id: I03fbdc7794a338a55b9dc64521915a8be247bf35 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2376045 Commit-Queue: Jamie Madill <jmadill@chromium.org> Reviewed-by: Jamie Madill <jmadill@chromium.org>
