Steps to reproduce: 1. Open Fennec; 2. In Top Sites have more than 8 sites in order to enable scrolling; 3. Fast swipe left or right in the Top Sites section of the tab. Expected result: If the first or second panel of the Top Sites is displayed the user can't scroll any longer in that section and the entire page is scrolled Actual result: The Top Sites area is still scrollable.

This only affects users who scroll really fast through top sites and it's already a P5.

All open Activity Stream bugs are moving from the whiteboard tag, "[mobileAS]", to the Firefox for Android component, "Activity Stream", so that I can keep better track of these bugs as the new triage owner; I will send out an email shortly with additional details, caveats, etc.
