    <thetext>Hi Team,

It seems we are doing unnecessary rounding here:

https://searchfox.org/wubkat/rev/d81c1b27d2ba489e7f086c79af5da4235e0308ee/Source/WebCore/rendering/HitTestLocation.cpp#31

and fixing it progress - https://wpt.fyi/results/css/cssom-view/elementFromPoint-subpixel.html?label=master&amp;label=experimental&amp;aligned&amp;q=elementfrompoint-subpixel

Just raising, so we can fix it.

Will do draft PR to see fall out on EWS.

Thanks!</thetext>
