308389 - Copy via Drag&Drop+Alt misses "Plus" (+) icon (on Mac only?) - Regression

Status: NEW

(Thunderbird :: Mail Window Front End, defect)

Description

Regression
Bug seen in Thunderbird 1.5 beta on Mac OS X 10.4;
works in Thunderbird 1.0.6 Mac

Reproduction:
1. Select one message in your thread pane
2. Drag it with your mouse on a folder
3. While still holding the mouse button, press the "Alt" keyboard key,
   then release mouse button
5. Open target folder to check if the message is there

Actual result:
In step 3, you see no visual indication of the fact that you pressed the Alt key
and that this has a meaning.
The message *is* being copied (not moved), though, if you use Alt.

Expected result:
As in 1.0.6 and seamonkey, a plus (+) icon appears in addition to the message
proxy icon, to signal me that the message will be copied, not moved.

Somebody please confirm status on other platforms. Until then, I assume that
it's Mac only and I set pp keyword.

related firefox bug 302403?

Could one of these two bugs moved to Core, and the other one be marked as a dupe?
