Plugin installation from a non-main git branch fails

[maxigaz]

I've been using a plugin with a specific branch (i.e. not main or master) through tpm. I have the following added to my ~/.tmux.conf:

set -g @plugin 'maxigaz/tmux-onedark-theme#pr-no-default-time-date'

This doesn't seem to work on the device I'm trying now; if I press Ctrl + I, I get a download fail error for tmux-onedark-theme.

However, if I do the following, it works:

1. Edit ~/.tmux.conf so that it contains set -g @plugin 'maxigaz/tmux-onedark-theme'.
2. Press Ctrl + I.
3. Navigate into ~/.tmux/plugins/tmux-onedark-theme.
4. Run git checkout pr-no-default-time-date.
5. Restart tmux.

I'm using tmux 3.4 on Arch Linux ARM.
