Steps to reproduce:

I made an svg with width: 100% height: 100%  and viewbox="-1 -1 2 2" and put a circle cx=0 cy=0 r=0.01 inside a <g transform="scale(50,50)">

Here's an example:

Actual results:

Mouseover events are triggered in regions outside the circle and mouseout events are triggered for regions inside the circle

Expected results:

Mouseover events should only be triggered when the mouse is over the circle, and mouseout events for outside the circle
