Describe your question, feature request, or bug.

Using kitty 0.27.1, I have image preview setup in lf file manager, with vim-lf plug also installed.

Launch kitty image preview with kitty +kitten icat image.png shows:

Error: Terminal does not support reporting screen sizes in pixels, use a terminal such as kitty, WezTerm, Konsole,
 etc. that does.

kitty +kitten icat --print-window-size says 0x0

Obviously this doesn't need lf to reproduce.

Steps to reproduce

Using the minimal vimrc

set nocompatible
set hidden
set termguicolors
set runtimepath^=$HOME/.config/nvim/plugged/vim-floaterm
filetype plugin indent on
syntax on

Launch floaterm with: :FloatermNew!

In the terminal launched, run kitty +kitten icat someimage to see the error message
