ysiw just goes into insert and types a 'w'

[Christensen-John]

I've been trying to get this to work. The more basic vim.surround commands work. When I type ys and then follow it with i the i is interpreted as going into insert mode.

Edit, it turns out that it works after I remapped j and k to swap around. Why would remapping those keys affect this command which doesn't use a remapped key?

Here is the remapping I used:
noremap k j

noremap <C-w>k <C-w>j

noremap <C-w><C-k> <C-w>j

noremap j k

noremap <C-w>j <C-w>k

noremap <C-w><C-j> <C-w>k

I split that onto different lines or else VSCode would not work with the remappings.
