Comment 4 Kimmo Kinnunen 2021-11-30 01:38:54 PST
Later on, we should set the variable on GraphicsContextGLANGLE constructor.

Do these tests not run on EWS?
Comment 5 Fujii Hironori 2021-11-30 02:43:42 PST
WinCairo doesn’t have a EWS testing bot yet. If you want to test your patch before landing, let me know.
