Automatically mark as read delay not working
As soon as I double-click on a message that is marked as unread it immediately marks the message as read. Under Tools - Settings - General - Reading & Display my setting indicates it is supposed to automatically mark message as read "after displaying for 10 seconds". I've tried turning that setting on and off, changing the delay value and starting and stopping the application but no matter what I do, double-clicking an unread message immediately marks it as read. It's as if that setting does nothing.
I am running Thunderbird 102.5.1 (64-bit) on Windows 11 22H2.
