Created attachment 445412 [details] testcase.html Pointer events, such as onpointerdown, onpointerup, onpointerenter and onpointerleave, are not triggered on iPhone Safari. How to reproduce: 1. Host the attached testcase.html file on a server. 2. Load the testcase.html page on iPhone Safari from the server. 3. Tap the black circle. Hold the finger down, the circle should become green (triggered by onpointerdown). 4. Release and the circle becomes dark gray (triggered by onclick). Step 3 fails on iPhone Safari. The circle doesn't become green, which means that onpointerdown is not triggered. It does become dark gray when the touch is released, so onclick is correctly triggered. Other pointer events are not triggered either (note: they are not tested by the testcase to keep it simple). Tested to fail on iOS Safari 15.1. All events are triggered correctly on Mac Safari 15.1 (16612.2.9.1.30, 16612).
