Right click on a Trial Spawner with a mob egg.

Can confirm. Related to MC-266487.

The spawner changes its state every game tick (proven by running /tick freeze and then /tick step 1t while the constant changing of states is occurring).

I was in Creative mode when testing this, by the way.

Found out that the same thing happens when switching from "peaceful" to any of the other difficulties.
