Problem / Steps to reproduce
I use vim inside tmux. Often, I want to find uses of some function. When I :Rg, sometimes the results get cut off so much that they're not helpful. I maximize the tmux pane, but the fzf window doesn't resize, so I have to relaunch it and type my search again. This is annoying. See video:

Desired solution: when vim resizes, the fzf panes should redraw and fill the newly available space.
I'm not sure if Vim provides an API to resize a popup window. If it doesn't, we're out of luck.
A better option I think (which I use) is to make fzf start in a tmux popup instead of a vim popup, so it can be larger than the current pane, by setting g:fzf_layout option like this:
if exists('$TMUX')
let g:fzf_layout = { 'tmux': '90%,60%' }
endif
