Goyo makes vim-buffet "go away"

I'm not sure if this is a problem that vim-buffet or Goyo should solve, so I'm just going to file an issue in both places 🙂

When activating Goyo, it seems to "reset" the tab-line that I have set up with [vim-buffet](https://github.com/bagrat/vim-buffet). Here's a recording of the issue: https://share.getcloudapp.com/5zuGQorD

Is this something I could get Goyo to "stop"? I'd like it to keep vim-buffet around if at all possible.

Reproduce the issue by activating Goyo while vim-buffet is configured, using the linked recording as the expected behavior reference. Inspect how Goyo changes the Vim tab-line and determine whether the tab-line can remain available; done means vim-buffet stays visible after Goyo is activated.
