Needs similar treatment as we do for positioned nodes.
Comment 2 Simon Fraser (smfr) 2019-04-09 17:16:34 PDT 
May need the same thing for position:fixed?

Is this another case of missing positioned nodes in scrolling tree?
Comment 6 Simon Fraser (smfr) 2019-04-10 09:22:30 PDT 
No, the sticky node already acts as the 'positioning' node, so we need to have some similar logic for sticky that we have for positioned nodes.

Scrolling via the blue box works fine, it just flickers horribly.
Comment 8 Antti Koivisto 2019-05-16 15:25:15 PDT 
Flickering is covered elsewhere so I think this can be closed.
