SVGGeometryElement: isPointInFill() how is pointer-events used?

[xBZZZZ]

https://developer.mozilla.org/en-US/docs/Web/API/SVGGeometryElement/isPointInFill:

Normal hit testing rules apply; the value of the pointer-events property on the element determines whether a point is considered to be within the fill.

What does that mean? pointer-events='none' doesn't change result of isPointInFill in my test: https://jsbin.com/kopefuzace/1/edit?html,js,output

I asked similar question in pull request (mdn/content#35746 (comment)) but no answers there.
