fzf behavior changes when capturing its output

The following command works fine as expected: find ~ -type f | fzf -m --preview-window=up:30% --header "ctrl-f: selected all and exit" --bind "enter:execute(less {})" --bind "ctrl-f:select-all+accept" But if I add >outfile.txt or | xclip to the end of this command, all --bind options that contain execute action are ignored. Is this a known fault? Is there a way around it?
