Build ID: 20111005130150

Steps to reproduce:

1. Open up a window without tabs-on-top with say 3 tabs
2. focus the middle tab
3. Hold left mouse button down on from bottom of the tab(below text) and move a straight line down() below the tab bar(about 5 pixels into the webpage)
4. Release and go straight up

(I know this is a little hard but if you're using a touch pad this is a lot easier)

Actual results:

The tab thinks I am still dragging it even though I have released my mouse(I made sure I did)

Expected results:

The tab should stop dragging.

I tried this on Nightly 10.0a
Windows XP SP3 Home

I can reproduce this in Beta 8.0 on OS X 10.7 Lion.

Bug 675340 is relevant. There seem to be at least two different ways of triggering this phantom drag.
