Explanation

When in single-value mode (or select if you prefer) with enforceWhitelist=true I would like to avoid to have the ability to leave the input empty; it should always be set to some value (like a real select).
Because I don't see any other way I used an hook to reject the deletion, it does work fine but the text is deleted anyway no matter what.

There should be a fix for this or even better when in this mode a value should always be required to avoid leaving the input empty (and so avoid backspace and remove the 'x' button).

EDIT: To point out why it works fine, I see that by sending the form the value is indeed there and not deleted.
EDIT 2: Just to add another thing, a workaround is to use

callbacks: {
	remove : (e) => {
		e.detail.tagify.addTags(e.detail.data.value);
	}
}
