Kitty integration reverses input direction

[LazyStability]

After a reason update to this plugin I now have the problem that the navigation from a window on the left to a window on the right does not work if the window on the left is a nvim window. However if I try to navigate to the left from the window on the left I land on the right.
An analog problem exists for up, down movement. This problem is only present when navigating from a nvim to a kitty window. All other movement as well as resizing work as expected.

I have manually update all the required kittens and checked my previously working config against the one from the readme but couldn't find anything wrong besides differing keybinds.
kitty.conf

kitty_mod           ctrl+shift
# Kitty navigation
map kitty_mod+j neighboring_window down
map kitty_mod+k neighboring_window up
map kitty_mod+h neighboring_window left
map kitty_mod+l neighboring_window right

# Unset the mapping to pass the keys to neovim
map --when-focus-on var:IS_NVIM kitty_mod+j
map --when-focus-on var:IS_NVIM kitty_mod+k
map --when-focus-on var:IS_NVIM kitty_mod+h
map --when-focus-on var:IS_NVIM kitty_mod+l


# the 3 here is the resize amount, adjust as needed
map alt+j kitten relative_resize.py down  3
map alt+k kitten relative_resize.py up    3
map alt+h kitten relative_resize.py left  3
map alt+l kitten relative_resize.py right 3

map --when-focus-on var:IS_NVIM alt+j
map --when-focus-on var:IS_NVIM alt+k
map --when-focus-on var:IS_NVIM alt+h
map --when-focus-on var:IS_NVIM alt+l

Here are some logs, I don't know if they are helpful:

Could you please try to set at_edge to 'stop' or 'split' in your conf?

at_edge = 'wrap' is not supported on Kitty terminal but it is the default for the plugin - I will raise a change for that.

[LazyStability]

Setting it to 'stop' does work as intended. Thank you.

'Split' does create a new split, which is not something I'd want. Is that expected behavior? Didn't find anything on while skipping through what I think is the manual.

[maatthc]

As far as I know, yes - I might be wrong tho..

[mrjones2014]

Yes the split thing is a feature that has been asked for in the past. If you don't want that, then just use stop. Thanks for jumping in here @maatthc

Raised PR to address this.
