1442076 - Stuck highlight when e-mail arrives during message drag-and-drop

Status: RESOLVED DUPLICATE of bug 458570

(Thunderbird :: Folder and Message Lists, defect)

Description

[Matthew Kidd]

Attachment: Sticky highlight on folder pane.png

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:58.0) Gecko/20100101 Firefox/58.0
Build ID: 20180206200532

Steps to reproduce:

E-mail arrived in my Inbox during a drag-and-drop operation of e-mail (four e-mails) to a folder. At the time I had the mouse cursor over the destination folder which was highlighted in blue but had not yet completed the drag-and-drop by releasing the left mouse button.


Actual results:

See the attached partial screenshot of the folder pane. Thunderbird is in the Vubridge folder but the Skiing folder, which was the destination folder for the aborted drag-and-drop operation, remains highlighted.


Expected results:

Drag-and-drag operation should not have been aborted by the arrival of new e-mail. And if it is to be aborted, it should be aborted cleanly, not leaving the destination folder of the drag-and-drop highlighted.

perhaps related to bug 458570

Comment 2

Yes, these seem to be related, though in bug 458570 it seems to be the e-mail item that has the stuck highlight ("toast" in the poster's jargon), rather than the destination folder. FWIW, for the present bug was also exhibited with IMAP folders.
