I guess I shouldn't be snarky - I appreciate the browser vendors claim they are working on getting all major browsers to behave the same. That said, I feel like they might be concentrating on the wrong areas. Like there are some super core areas that need to be covered.

Half a year ago made tiny "draw with pointer" demo. Tested on desktop Chrome/Safari/Firefox and iOS. Turns out it didn't work on Android. I don't have an Android to test on. But, it was literally the most basic pointerevent code. I wasn't doing anything out of the ordinary or near any edge cases.

Filed a bug, zero movement.
