fast/canvas/canvas-draw-canvas-on-canvas-flushing-order.html

Is a flaky image failure on BigSur.

History: https://results.webkit.org/?suite=layout-tests&test=fast%2Fcanvas%2Fcanvas-draw-canvas-on-canvas-flushing-order.html

It looks like there are two different diffs depending on the platforms.

The test running on Big Sur E wk1 Release is failing because of a black expected image:

https://build.webkit.org/#/builders/48/builds/5311
https://build.webkit.org/#/builders/48/builds/4743

I think the image failures on other platforms are real:
