Clicking on unread messages makes first conversation thread expand

Hello,

As per title, when I step on a new message not belonging to the first thread, the first thread expands automatically. This does not happen when I step on an already read message. I also tried to mark old messages as unread, and the same thing happens. Apparently, it started doing this today, which sounds weird as Thunderbird last updated on the 15th, but I didn't notice this type of behavior before today.

Thunderbird version: Thunderbird Windows MSIX package 1.0 - 140.8.1esr (64 bits)
