If you place a NOT gate, you can negate its input:
However, the bubble is not drawn, and it does not appear to change the behavior of the gate:
However, it does shift the gate over as if there was a bubble. Below is with the mystery property set to false:
Normally I would try to make myself useful and fix this, but I got stuck on the following:
It's tempting to check if there are 1 inputs in GatePeer, but in the future we could add a gate that takes 1 input but for which a bubbled input is useful (no clue what that would be)
I'm not sure if (1) would change the x/y of the gate, breaking existing circuits with the mystery property set to true (you would know this better)
