Problem / Steps to reproduce

STEPS TO REPRODUCE

1. Make bash script file lag.sh with following content

   
   #!/bin/bash

echo /etc/fstab | fzf --bind='enter:execute( sudoedit -- {} )'

2. Run the script `$ ./lag.sh`
3. Press Enter
4. Enter your user password to authorize sudo
5. Press and hold an arrow key to see cursor moving. Play with the arrow keys. It's easiest way to see the lag. Actually during work, this lag is very notable.

ACTUAL RESULTS
Cursor is stuttering, sometimes for very long time.
