Support `fzf-tmux` about extrakto

[laktak]

extrakto uses popups, this keeps the zoom state the same:

tmux - popups require 3.2, otherwise extrakto will open in a split window.

Are you on an old tmux?

[liangkarl]

Uh, no...
I'm using tmux 3.3a and 3.4

As you said, the popup window would not bother the zoomed window, but the split window did.
It's easy to reproduce that simply change the @extrakto_split_direction between the two values in a zoomed window,
set -g @extrakto_split_direction 'v'
and
set -g @extrakto_split_direction 'p'

Also, if we try to use ls | fzf-tmux in a zoomed window, fzf-tmux would keep the zoom state.

I've tried to modify the script by removing the tmux window-splitting command and replacing fzf with fzf-tmux, but somehow tmux would become "no response" until I killed the fzf process.

[laktak]

In that case it is working as expected. Please use the popup window.

[liangkarl]

Okay, got it.
Actually, in my case, the popup window is too small to show a long file path picked up from some project compilation messages. Also, it doesn't look good to set the popup window to 100% width. That's why I switch to the vertical split window instead.

[laktak]

vertical split has other drawbacks, that's why we switched to popups by default.

fzf doesn't want to do horz scrolling either junegunn/fzf#577
