`Minibuf-X` appears in Treesitter buffers

[Icy-Thought]

Something is not working properly within the (centaur-tabs-group-by-projectile-project) defun to such an extent that I am somehow able to see hidden buffers within Centaur-Tabs when inside a buffer that is using tree-sitter.

For testing purposes try the following snippet from my personal config: (relies on elpaca, modify as desired)

[!NOTE] If you only remove (centaur-tabs-group-by-projectile-project) from the equation, then the buffers won't appear; as expected.

I'll look into it!
