Wow, this is very surprising - I would have expected this to be a performance win in scrolling tests. I'll investigate these first thing Monday morning, thanks for the alert!

This is addressed by the patch in https://bugzilla.mozilla.org/show_bug.cgi?id=1523210.
The try run [1] looks to restore those talos numbers to what they were previously, if I'm comparing correctly.
