STR:
- Press screen with the first finger (do not release it)
- Press with another finger.
Actual results:
A duplicated pointerdown event is fired for first press.
Expected results:
There should only one pointerdown event fired for first press.

I wonder why (manual) wpt tests for pointer events didn't catch this.

This is a major improvement for ARM arch and Windows, I think it's worth uplifting to 66.
Edgar, can you please prepare a uplift request?

Bug 1521082 - Don't dispatch pointer event if the touch in touchstart event is already registered;
Fix for pinch to zoom on touch screens, let's uplift for beta 6.
Is this something that never worked correctly in this case, or, is it a regression?
Or, maybe this site changed recently?
Thanks for adding new tests, too!

I am not sure if site changed recently.
For pointer event, this is not a regression, it is something that never worked correctly.
