--- Comment #3 from Simon Pieters <simonp@opera.com> ---
So it's 50/50. :-(

It seems .pageY contains potentially useful information in Gecko.

Searching on github reveals that there are some pages that use it to
record/store scroll position:

https://github.com/search?l=javascript&q=onscroll+pagey&type=Code&utf8=✓

It seems less risky for WebKit/Blink to switch to UIEvent than the other way
around, so I suggest we change scroll to use UIEvent.

Relatedly, in Gecko, .pageY is on UIEvent, not on MouseEvent as the current
spec says. Though Chromium has it on MouseEvent.

Rick, do you have opinions?
