• vim-which-key version: 4cbfe3b

Describe the bug

My screen seems to be vertically split with only one line at the top being active. In this line I can move up and down but not left and right and can't edit text. If I invoke which-key again this error is displayed:
Error detected while processing function which_key#start[49]..which_key#window#show[9]..<SNR>53_show_old_win[2]..<SNR>53_open_split_win[2]..<SNR>53_split_or_new:

To reproduce

1. Move into a treesitter context with the nvim-treesitter-context plugin.
2. Invoke vim-which-key
3. Exit vim-which-key with

If you turn on the floating window feature, it seems that this issue goes away. I'm currently using that in order to keep using both plugins for now.
