The failures quoted in comment 0 are things like "Top of circle should hit - got null, expected [object SVGCircleElement]" which corresponds to this in the test:
https://searchfox.org/mozilla-central/rev/56dd89bcf4d3b85f66621e89eac6e2936ad382d9/dom/svg/test/test_pointer-events-3.xhtml#23-24

var elementFromPoint = document.elementFromPoint(originX + 150, originY + 52);
is(elementFromPoint, circle, "Top of circle should hit");

The test does this hit-testing using document.elementFromPoint. The fact that it's returning null means Firefox thinks the hit coordinates are outside of the viewport, I think? At least, on MDN for this element, that's the only mention of null:

If the specified point is outside the visible bounds of the document or either coordinate is negative, the result is null.

(We can poke more if this happens more often. This feels like it could be some sort of race condition with getting the iframe set up with the right viewport size, or something like that.)
