feature request: track selection across reload-sync

[yorickvP]

• I have read through the manual page (man fzf)
• I have the latest version of fzf
• I have searched through the existing issues

  • Mac OS X

  • zsh

Problem / Steps to reproduce

I'm using a single selection, and I have a binding that sorts my input in various ways:

    --bind 'ctrl-s:execute-silent(track+reload-sync<'"$FZF_DEFAULT_COMMAND" | sort -hk3'>)' \

However, this loses the current selection and instead selects whatever line is at that position in the new ordering.
I would like fzf to track of the currently selected line when reload-sync completes and it's still in there. How could I achieve this?

What's the exact use case?
