(async () => {
	const outer = await Folder.create({
		name: "Outer",
		type: "Actor",
	});

	const inner = await Folder.create({
		name: "Inner",
		type: "Actor",
		folder: outer.id,
	});

	const actor = await Actor.create({
		name: "Repro",
		type: "character",
		folder: inner.id,
	});

	await outer.delete({deleteSubfolders: true, deleteContents: true});

	location.reload();

	// observe that the structure `Inner/Repro` still exists
})();
