Load attached testcase with webrender. Move the mouse over the red square and wheel-scroll.
Expected: nothing scrolls (as in non-webrender)
Actual: the subframe scrolls
The patchset I'm working on for bug 1389149 fixes this, but filing this as a separate bug to track it and ensure it gets fixed one way or another.

The reason this happens is that with non-WR, nsDisplayFixedPosition does one thing and then FrameLayerBuilder later fixes it up [1]. With WR we do the nsDisplayFixedPosition thing but then don't do the fixup so we end up with the wrong scroll target on the fixed-pos layer scroll data.
