close_window now behaves like closing the whole tab

[subokita]

Describe the bug the close_window function in config file, used to close the window (of the horizontal / vertical layout). But somehow after the recent update (Version 0.32), it tries to close the whole tab (asking me for confirmation "Are you sure you want to close this tab, it has 2 windows running?")

IIRC, it was still working properly in version 0.31.

map cmd+w close_window

To Reproduce Steps to reproduce the behavior:

1. update kitty.conf file with map cmd+w close_window
2. update kitty.conf file with map cmd+d combine : new_window_with_cwd : goto_layout horizontal
3. cmd+d on the kitty tab
4. then cmd.+w on the kitty tab
