Details
+++ This bug was initially created from Bug #1505321 comment #7 +++
Steps to reproduce:
- Open https://marci4.github.io/firefox/pointerevents/preventdefaultandmove.html
- Put one finger inside the left rectangle, and one inside the right rectangle and move both fingers together down/up.
Expected results:
Both rectangles should be getting detected
Actual results:
Only the move of one rectangle (left or right) is getting detected.
(When I am not using preventDefault() everything is getting detected correctly.)

The bug is now triggered on X (formerly twitter) when opening an image and trying to zoom it.
Imo this adds a bit of urgency, hence the report :)
