Form Editor UX: Do not discard field directly if user clicks outside editing modal

[knomepasi]

As in the title; this can be frustrating when adding/editing especially more complex fields like radiomatrix.

Action could be either disabled completely or a confirmation modal ("Do you really want to discard field X?") added.

This would be modal on a modal, which I generally detest.

A better solution would be offering some kind of visual cue that the modal needs to be acted upon (at least cancelled/closed explicitly).

Or we could just disable close on click outside.
