>>> My Info: Win7_64, Nightly 45, 32bit, ID 20151206030448
STR_A:
1. Open http://www.megalyrics.ru/lyric/portishead/give-me-a-reason-to-love-you.htm
2. Make sure that page is long enough to be scrollable
3. Middle-click on the right side of the background at the top of the page
Result: Background quickly twitches to the right and back
Expectations: Background should stay still, just like in normal (non-e10s) mode
STR_B:
1. Open "testcase 1"
2. Make sure that page is long enough to be scrollable
3. Open console (Ctrl+Shift+K)
4. Middle-click on the page
Result: Console reports strange numbers in clientX/clientY. I've got the following numbers:
> mouseout { target: <html>, buttons: 0, clientX: 498, clientY: 124, layerX: 498, layerY: 124 }
> mouseover { target: <body>, buttons: 0, clientX: 498, clientY: 124, layerX: 498, layerY: 124 }
> mouseout { target: <body>, buttons: 0, clientX: 14, clientY: -57, layerX: 14, layerY: -57 }
> mouseover { target: <html>, buttons: 0, clientX: 14, clientY: -57, layerX: 14, layerY: -57 }
Expectations: No strange numbers like "clientX: 14, clientY: -57". I clicked mouse ~~in the middle
of the page, so I expect to get numbers like "clientX: 498, clientY: 124"

Does this happen with APZ disabled as well? I see that it's marked status-firefox45:affected, but 45 doesn't have APZ enabled. It's also marked blocking apz-desktop though which is conflicting information.

So here's the old version of that page:

It'd be good if somebody saved it _completely_ somehow, because the mechanism may differ from
comment 0 (which OFC is a bug itself). My suggestion is to keep this bug about mouseover/mouseout,
and then check if that will fix old megalyrics widget.

I can confirm that APZ enabled/disabled doesn't affect this bug.
