For some reason, when I installed 2019.3 beta 2, when I read the status line and/or navigate with up/down arrow keys, the read/unread status of message is inconsistent or incorrect.
I wonder if anyone else is experiencing this issue. I am using Thunderbird 60.4--the last fully compatible version of Thunderbird.

I Say: "I'm as happy as a stow away chimpanzee on a banana boat!"
