kitty outputs a lot of text when an ssh connection is interrupted

Describe the bug I use alias ssh="kitty +kitten ssh" as suggested. When I interrupt a hanging SSH connection, it outputs a lot of text like this to the console:

: 1685136788:0;KITTY_DATA_START
: 1685136788:0;OK
: 1685136788:0;H4sIAAAAAAAC/+y9fWwcyZcY1lzpd7/biWMbiOMvOZf6NYdLjsQZzheHErmzuxJJrfhbieRPpFa7S/I36umu4fSPPd2zXd0cUhT3zg6SABcghhMEMRwbB9iwgziGA5/zYRhJnA/k4ASIkSAG8oXgDCOwESBBEifBJf7jFNR7Vd3VX0NJ++HbOxHSzFR31atXVa9evffq1atd4+wBNSzqs1p9yTICo8aG2jf8V8e/ou96o9WMfsPzRqPdaWrkTP

(This is from my ~/.zsh_history.)

It seems the only way to handle this when it happens is to close the window completely. It's especially painful because it interferes with zsh-autosuggestions and pollutes my history.

To Reproduce Steps to reproduce the behavior:

ssh <host>
Interrupt (^C) before the connection is established.
Observe.
