CC'ing sdy since https://chromium-review.googlesource.com/c/chromium/src/+/636391 in the changelog looks suspicious.

Summary: CursorRendererMacTest.CursorDuringMouseMovement is flaky (was: CursorRendererMacTest.CursorDuringMouseMovement is failing)
Also, cc'ing some of the owners.

Testbot went green in https://uberchromegw.corp.google.com/i/chromium.mac/builders/Mac10.11%20Tests/builds/17227, so it seems that test is just flaky.

Ran the test locally for more than 1k times and couldn't reproduce this issue.
Basically cursor_renderer_mac_unittest.mm & cursor_renderer_mac.mm haven't been touched again since they were landed half years ago. So I guess the most possible reason is the bot (OSX) didn't respond the system call "CGWarpMouseCursorPosition()" at that moment for some reason. 

I would suggest keeping it as is and let me know if it happens again.
