I think the issue is that it triggers when there is even a tiny piece of dirt in there. Ie. the pins aren't shorted, but there is some damp particle of dust in there causing a 10 Megaohm connection which would do no harm whatsoever. Happens a lot for people who leave USB-C cables in the bottom of bags and they get dirt in the connector (and possibly the residue from that beer that exploded in your bag last year and the sugary water never quite evaporates)
