Bug 1560843 [wpt PR 17351] - Don't round hit test location in HitTestLocation::RectForPoint, a=testonly 

Automatic update from web-platform-tests
Don't round hit test location in HitTestLocation::RectForPoint

HitTestLocation rounds the hit test location to the closest 1x1 rect
for no good reason, causing some confusing hit test results. Hence,
this patch removes such rounding.
