Tab completion followed by backspace leaves characters after the prompt

[fathergoose]

Describe the bug When using tab completion at the command prompt (zsh) in kitty 0.26.0 the text added for the completion cannot be deleted. Despite the text not being able to be deleted it (the text) is not included as a part of the next command.

To Reproduce Steps to reproduce the behavior:

1. Open kitty
2. Type a command e.g. vim
3. Type TAB to provide a list of completion options
4. Attempt to erase the tab completed text
5. The text does not completely erase, but it is also not included in any command

Screenshots Here I type vim <tab> then hold backspace until it stops (doesn't go all the way to the prompt). Next I run ls to show that the "ghost text" has no effect.

Additional context Reproduced with kitty --config NONE. I skipped the GIF, but the same series of actions leads to the same behavior as described above.

Happy to provide more information. Thanks for writing my favorite terminal emulator!

almost certainly a dup of #5439 just update to 0.26.1 and you will be fine
