We should consider merging
https://chromium.googlesource.com/chromium/blink/+/5572128a489527f3808bd307531f9c4c7a7f07b3

Based on what is currently done throughout the LayoutTests/, there
are 2 ways to reduce the flakiness of a :hover test:
* Force layout before and after moving the mouse (especially since
some tests claim that we don't track the mouse before first layout).
* Force a click after moving the mouse.

This change implements the first option as the second one didn't work
for these tests (I remember that it helped in webkit.org/b/81460
though).
