Description:
fast/canvas/canvas-scale-strokePath-shadow.html

This test has been failing on macOS for a long while.  I pulled the failure off the bot test run, which did not appear on the layout test results page.  The diff is manually comparing text diff with test expectation. 

Reproduction on the bot:

This looks like a re-baseline.

The test is still failing on other macOS versions. I think that the test needs to be fixed - it makes no sense to waste bot watchers' time constantly rebaselining from one failing result to another.

Agreed.
