Add a visual indicator for when APZ is disabled by scroll-linked effects
58 bytes, text/x-review-board-request
Discussed this with Markus today, we should have a visual indicator for when APZ is disabled by scroll-linked effects. That way we can turn on the apz.disable_for_scroll_linked_effects pref when running locally and get a sense of which pages get APZ disabled even though they don't have any visual glitches (i.e. the false positive rate).

I'm running Nightly with this enabled, and it didn't take long for me to run into a site where APZ gets disabled because of a scroll-linked effect (fake-sticky-positioned toolbar). If I re-enable APZ on this site the behaviour looks decent, not noticeably laggy at all. Sites like this swing the balance in favour of leaving apz.disable_for_scroll_linked_effects as false. https://www.softwarehamilton.com/2016/06/29/python-meetup-on-july-6th/
