yeah, something's wrong in the popup position calculation.

The STR is not that simple, so it is unlikely that many people will encounter this, but the result panel is then misplaced for the lifetime of the browser. So once someone hits this bug, it's going to be annoying for a long time.

Well, specially for you I have simpler scenario using "chain bugs" technique
STR_3:
0. Open this bug 1276121, then bug 1276120 in the same tab.
1. Click in urlbar, type "c", press Alt+Left
2. Hover mouse over any suggestion

The panel twitches to the left. Step 0 doesn't count as it only creates a tab with history.

Yes, this needs fixing.
