Same issue: move your pointer here until you see a scrollbar, then stop moving your pointer: http://rbyers.github.io/eventTest.html The pointermoves never stop!

An overflow is not necessary, a simple canvas shall produce an unrelenting stream of pointer move events: http://codepen.io/emotionalpanda/pen/BpQazv Method: Move pointer/pen over canvas. Lay pointer on its side so it is not moving. "pointermove" events are continuously fired (line 29 through 32). Hardware is a Huion 1060+ tablet.

Looks like the bug got fixed, doesn't repro anymore (tried all 3 repros on Mac and Android). Marking as WAI. |
