Internal kitty shell has broken backspace when term != xterm-kitty #3870
Description
Describe the bug
If the term config variable is xterm instead of xterm-kitty, the internal kitty shell (shift-control-escape) seems to have something wrong with its line editing.
(I find it necessary to set term to xterm or similar, otherwise upon ssh to many hosts, they complain that xterm-kitty is not a known terminal type.)
To Reproduce
Steps to reproduce the behavior:
- Edit
kitty.confto setterm xterm - Start kitty
- Press shift-control-escape (with default keymap) to launch a kitty shell windowpane
- Type something
- Backspace to erase
- Instead of erasing, you get extra spaces
Screenshots
This is after typing "hello", then pressing backspace 5 times.
