Some entities seem to trigger it although I'm not sure why, we have a few sector exports that have it without a doubt, but can't freely share those on phabricator unless I make the ticket private (which is a bit overkill).
I have a simple one, that when imported and loaded seems to trigger it if you wait long enough (maybe an auto-save is required?): {F21177}
