All emails show up with this line "this is a draft message" under the subject line.

I have about a dozen accounts with over 50 folders, most with a matching filter. About 100k messages, taking up about 1G of disk space. All but one account is merged under my Inbox to have fewer duplicate In/Draft/Sent boxes eating up window space. I'm using 152.0.1 (aarch64) Release branch on a Mac OS X 26. All are POP accounts on a DreamHost server. At some point it started to show the draft message on every email, which means on incoming as well. I've had this phenomenon for years. Recently filtering has started to not automatically run on some emails forcing me to run the filters manually. I've run the repair folder options which does not seem to make any difference. Since switching to macOS 26 it also does not allow me to move Thunderbird child windows, they simply show up on the default location. But that's for another ticket.
