Description

Treesitter folds are broken, it only works if you manually set vim.opt.foldexpr to the specified value after a file is opened.
I'm not sure what is going on this file other than being that way to solve another issue?

Installation Method

NixOS Module (nixosModules.default)

Installation Method (Other)

No response

nvf Version

main

Reproduction steps

1. Set vim.treesitter.fold = true in your config.
2. Open a file with code
3. Try any folding options (i.e zA to toggle all folds)
4. See that no folds were registered.

Expected behavior

To be working by default without having to set foldexpr or any other fold-related options that seem to fix it.

Actual Behavior

No folds are registered, can't close or open folds.
