Byobu creates infinite spawn of “byobu-status -> tmux” children under tmux

When I launch Byobu, my System Monitor shows a new tmux process with a continuously growing set of byobu-status -> tmux children eating-up all my memory…

-> tmux
-> byobu-status
-> tmux
-> byobu-status
-> tmux
-> byobu-status
-> tmux
-> …
-> …
-> …
…
…
…

This continues with memory growing every second, and I can't find where the issue is being triggered.

Upon booting into the system, when tmux is launched on it's own before and separately from byobu, this issue WILL NOT happen in THAT tmux session. After byobu is launched for the first time and any subsequent time following that, tmux on it's own WILL cause this issue.

I don't doubt that it's a configuration issue in some rc file, but can't for the life of me find where it is…these are the files I've tried looking through:

~/.byobu/profile.tmux
