Initiating a drag event when nothing is selected causes a crash

[MewPurPur]

1. Hold the cursor pressed over an element in the list
2. Press Esc while still holding, to deselect the element
3. Drag the cursor around
4. Crash

It happens because of the static function 'filter_descendant_xids' at
res://src/utils/Utils.gd line: 113

the 'new_xids' array is empty
but at line: 113
you are assigning 'last_acepted' to a value don't exist: Out of bound exception

i honestly didn't explore the project code further
but a temporary quick fix :

static func filter_descendant_xids(xids: Array[PackedInt32Array]) -> Array[PackedInt32Array]:
	if xids.is_empty():
		return xids
	var new_xids: Array[PackedInt32Array] = xids.duplicate()
	new_xids.sort_custom(Utils.compare_xids_r)
	# Linear scan to filter out the descendants.
	var last_accepted := new_xids[0]
	var i := 1
	while i < new_xids.size():
		var xid := new_xids[i]
		if Utils.is_xid_parent_or_self(last_accepted, xid):
			new_xids.remove_at(i)
		else:
			last_accepted = new_xids[i]
			i += 1
	return new_xids
