[kovidgoyal]

works fine for me with:

echo test | kitten clipboard; kitten clipboard -g

[neurocyte]

Try this

echo -e '\e]52;c;SGVsbG9Xb3JsZA==\a'
echo -e '\e]52;c;?\a'

The second line should return the first line's value.

This works fine in previous kitty versions, ghostty and alacritty, but not in kitty 0.33.0. Am I doing something wrong?
