Description

Installed Lazyvim, no customization, just plain out-of-the-box install and nvim-treesitter-context installed via :Lazy
Opened long R file and Toggled TSContext active via keybinds ( leadert + u + t)

Treesitter context is not keeping the function header visible when scrolling down

Neovim version

NVIM v0.9.2 Build type: RelWithDebInfo LuaJIT 2.1.1694082368

Expected behavior

Steps to reproduce

1. install Lazyvim
2. .install nvim-treesitter-context using :Lazy interface
3. open a long R file
4. activate TSContext with keybindings: leader + u + t
5. scroll down file
