1906758 - Folder highlight not visible when dragging messages

Status: RESOLVED FIXED

(Thunderbird :: Mail Window Front End, defect)

Description

[inattee]

Attachment: Screenshot 2024-07-08 at 15.29.24.png

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:127.0) Gecko/20100101 Firefox/127.0

Steps to reproduce:

Drag and dropped a message from inbox to another folder in the folder pane list.

Actual results:

While dragging the message, the folder list becomes obscured by the outline of the message and it's hard to see which destination folder is being selected.

Expected results:

The destination folders should be highlighted on hover more prominently so they are seen more easily.

We think this is a regression.
Perhaps Mac only.
