585816 - no thumbnail when dragging tabs

Status: RESOLVED WONTFIX

(Core :: DOM: Copy & Paste and Drag & Drop, defect)

Description

[juan becerra [:juanb]]

While spot checking Fx 4.0b3 candidates. Thumbnails are missing when you drag tabs on Windows 2000.

Steps:
1. Install the latest Fx4b3 candidate
2. Open three tabs.
3. Click on one of the tabs and drag it to a different location within the tab strip or drag it onto the desktop

Expected: You should see a thumbnail appear as you start to drag the tag.

Actual: You don't see a thumbnail appear.

If you are dragging within the tab strip you do see the drop location indicator (little arrow), but if you drag the tab onto the desktop to detach it, you don't see it.

In both cases the actions are performed and the tab can be dropped.

Juan, I have seen a couple of Litmus results where people mentioned the same problem. I have contacted the reporter but never got back an (helpful) answer and I never was able to reproduce this bug. Are you able to constantly reproduce it? Does it only happen for you in the Win2k VM? Would it be possible for you to create a screencast which demonstrates this problem?

If this is indeed win2k only, it does not block.

Bug is still reproducible in a Win2k host environment.

Simona or Paul, can you please work to find a regression range for this issue?

Issue is reproducible ever since Firefox 3.6.16.

Does that mean the bug happens on Firefox 3.6.16 but not Firefox 3.6.15?

I could reproduce this on Firefox 3.6.15 and on Firefox 3.5.

Given comment 9, this is very unlikely a regression. Is this only reproducible on Windows 2000? If so, this is likely WONTFIX.

Yes, issue is only reproducible in a Win2k host environment.
