Editing over SSH not working with Home Assistant OS

[ralphioli]

Describe the bug
Basically what the title says. Whenever I try to edit any file with edit-in-kitty on Home Assistant OS over SSH, I see the following:

bash: local: `255': not a valid identifier
bash: local: `3618516': not a valid identifier
bash: local: `925696': not a valid identifier
bash: [: : integer expression expected
Waiting for editing to be completed...

Then nothing happens.

To Reproduce
Steps to reproduce the behavior:

1. Using the SSH kitten, connect to a server running Home Assistant OS with the official Terminal & SSH addon
2. Try to edit any file with the edit-in-kitty command
3. See error

Additional context

• My computer is running Fedora 36 with Kitty version 0.26.4
• The server I'm connecting to runs Home Assistant OS 9.3 with Terminal & SSH add-on version 9.6.1
• kitty --config NONE does not solve the issue

I dont know what home assistant OS is and I'm afraid I am not going to
install an entire OS to debug this. From the error message it sounds
like the version of bash is too old. If you have the ability to use a
more modern bash I suggest upgrading, or using an alternate shell, like
zsh or fish.

Otherwise at some point edit-in-kitty will be implemented using a static
binary rather than shell script, at which time this should be
automatically fixed.

I get the same Waiting for editing to be completed... as well. From Arch to Arch and Ubuntu. I've also noticed it happens whenever the file is longer than just a few lines.
kitty --version : 0.26.4
bash --version: 5.1.16
