I spent quite a long time trying to write an automated test for this but I don't think I can without having it fire synthetic scroll events at the scrollbar, which seems rather fragile especially with disappearing scrollbars. So I gave up :-(

Roc, can we have an uplift request for aurora? (33). Thanks

Bug 1022612 was backed out of 33 so no uplifts to 33 to fix its regressions are needed.
