It's unfortunate, but there were never any guarantees that the labels (such as
DP-1, or HDMI-3) would be stable. The number is just an iteration of how many
ports of a certain type are present, in the order they have been iterated. I
believe we've changed both the order and the ports that have been iterated in
the past. For example, we've discovered ways to ignore ports that aren't
actually there.

I'm inclined to close this as NOTABUG, but then again if you'd be into
bisecting it might be interesting to see *why* the labels changed this time.
