697743 - Drag events stop working in Aurora 9

Status: NEW

(Core :: DOM: Events, defect, P5)

This morning after I updated Aurora, I tested tab dragging (because I was aware of bug 690227).  It worked as expected, with the old insertion arrow rather than the drag animations.  But when I tried again a while later after opening/closing/navigating various tabs, dragging a tab had no effect.

When I click and drag a tab, nothing happens - no arrow appears, and all tabs stay in the same place.  Since then, it has remained broken.  I haven't yet tried restarting the browser to see if the problem goes away.  I did start up a second browser process with a different profile, and did not see the problem there.

I have the following add-ons enabled:

Browser Sign In 0.1.5
Bugzilla Tweaks 1.11.2
Firebug 1.9.0a4
Mass Password Reset 1.04
reallyremember 0.1

When I load any page, the following error from the BrowserID add-on appears in the error console.  I don't know whether it's related to this bug:

Error: An exception occurred.
Traceback (most recent call last):

This was intentional. See Bug 690227 and Bug 455694

This bug is not about the animations going away; it's about tab dragging being completely broken.  I can't re-order tabs at all.  See comment 0 for details.

With fryn's help, I figured out that all drag-and-drop events are currently broken in this browser instance (but work fine in a newly-started browser process from the same build).  For example, http://html5demos.com/drag doesn't work in the "broken" process.

Based on manually adding listeners in chrome using the web console, it looks like "dragstart" events are received, but "drag" and "dragend" events are never received.

This is on Ubuntu 11.04 using the XMonad window manager, for what it's worth.

Sounds like dragservice is missing unsuppress call somehow.
