[0.32.0] Multi-key mappings waits indefinitely for defined keymapping to be pressed

[mikesmithgh]

Describe the bug
I have a few multi-key mappings (e.g, map ctrl+w>j). If I press ctrl+w+any non-defined mapping (e.g., ctrl+w+w), then Kitty waits indefinitely until I press a defined mapping. In this case, j. This behavior changed from the previous version of Kitty.

My exact use case is that I am using smart-splits.nvim and when I press ctrl+w+ h or j or k or l, it uses smart-splits.nvim to navigate between Kitty and Neovim windows. But, if I am in Neovim and try to use ctrl+w prefixed mappings like <C-w>b or <C-w>w, then Kitty will hang until I press h or j or k or l.

To Reproduce
Steps to reproduce the behavior:

1. kitty --config mini-kitty.conf
2. nvim --clean
3. press <C-w>q
   Expected
   Neovim should close
   Actual
   Kitty waits until either h or j or k or l is pressed.
