Steps to reproduce: start loading a webpage in a tab that takes a while to load, goto another tab that has a scrollbar, click and drag the scrollbar thumb and keep the mouse down. By the time the other tab has finished loading the scrollbar no longer responds to mouse moves.

Regression range is http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=bf0fdec8f43b&tochange=912c6ae3b70c

From that bug 503943 seems like the most obvious candidate.

Paste enough text in the box so that you get a scrollbar. Click after the last word, then mousedown on scrollbar slider and move up and down, then, without releasing, move your mouse direction text box. You should see a tooltip. This tooltip will break the focus on the scrollbar.
