Custom status variables not working when status bar generated by running vim

[dvdmuckle]

I have a plugin that adds the variable #{spotify_track} as well as other Spotify variables. My status line looks like:

let g:tmuxline_preset = {
      \'a'    : ['#S', '#I'],
      \'b'    : '#W',
      \'x'    : ['#(mpc current)', '#{spotify_artist} #{spotify_status} #{spotify_track}'],
      \'y'    : '%H:%M',
      \'z'    : '#H'}

If I use :TmuxlineSnapshot to save this to a file and source it from Tmux, the status bar looks fine.

However, if I load up Vim, the status bar is overwritten, and the variables seem to disappear.

Is there a way to either fix this behavior or keep Vim from recreating the status bar?

where did you write the presets, inside the vimrc?

As an MWE, I have

let g:tmuxline_preset = {
      \'z'    : '#{track}'}

in my vimrc, and am using the tmux-music plugin.

I think the bug here is that when tmuxline looks at tmuxline_preset, it only looks at the predefined values it knows of, and does not try to get other possible variables that could be exposed. That's why taking a Snapshot and putting in the tmux.conf is a workaround, since those variables will be exposed there.
