Plugin redraws screen when leaving nvim focus in tmux marking the window as having new activity

[erikw]

Hey,

this is a cool plugin! However I've needed to disable it unfortunately as it does not play well with tmux. When switching to another window in tmux, it seems like the window just left where nvim is, that this plugin redraws the screen. This causes tmux to alert that something has changed (new output) in the window that was just left, and also marking it as having new activity in the window list.

See the attached video for a demonstration.

The expected behavior, which is the case when this plugin is not used in nvim, is that there is no nvim activity when leaving the window, thus no false activity notifications.

My system:
nvim: 0.8.1
OS: macOS 12.6
vim-numbertoggle: latest version
