Local - Remote keybinds not working

[Just-Insane]

When attempting to use the local to remote keybindings, nothing seems to happen.

I have added the keybindings settings from https://gist.github.com/samoshkin/05e65f7f1c9b55d3fc7690b59d678734 to my ~/.tmux.conf.local file on my local machine, and to ~/.tmux.conf.remote on my remote machine.

When I SSH into the remote machine, tmux is automatically started and I get a status bar in the bottom as expected from ~/.tmux.conf.remote.

When I press F12, the local status bar (at the top) changes to Grey (I don't get an "OFF" icon, but that might be due to other tmux config), and when I press CTRL-A it is captured by the local tmux instance, not the remote instance.
