Looks a lot like 'tiling-assist...@ubuntu.com' is to blame. Hopefully it's not enabled by default in lunar final.

Additionally, placement of new windows seems random and unpredictable. I've attached a video to demonstrate this when I launch gnome-console using `CTRL+ALT+T`. You can see sometimes it is full screen, other times its in the top left quadrant, and then when i spawn an additional window the previous window's size changes. I am experiencing the same behavior with Files.
