This bug tracks APZ related work that needs to be done for WebRender on Android.
This is mostly WebRender implementations of APZ features that are mobile-specific and which we therefore haven't cared about so far (prior to bringing WR to Android).
- Implementing the
setVerticalClipping API (used by GeckoView to implement Fenix's dynamic toolbar) for WebRender (bug 1583380)
- Getting WebRender's
position:sticky implementation to behave well in the presence of pinch-zooming (bug 1569339)
- Getting fixed-position hit testing working correctly with WebRender (basically, the WebRender equivalent of bug 1522714)
There are probably other things I'm not thinking of right now.
