## Problem / Steps to reproduce

Unable to run a `--bind 'change:reload(sleep 0.1; $RG {q} || $true)'`
for some reason ripgrep, fd work but any other command including sleep doesn't
`[Command failed: sleep 0.1; rg --column --line-number --no-heading --color=always --smart-case [^"string_to_search"^] || True`

every time i change a word i need to wait for it to finish, in a larger project this can take a long time.
I tried looking through the wiki for a binding that could interrupt ripgrep or disable search when quay is empty but found nothing, also tried running execute on a keybinding but that also returned command

## Desired Effect
Stop rg from constantly searching on each key press, make it search for nothing when empty.

Start by reproducing the --bind change:reload command in PowerShell and compare it with the working ripgrep and fd cases. Read the fzf manual and wiki sections on reload and execute bindings; the issue is done when an empty query avoids the search and the intended command runs reliably on Windows PowerShell.
