Well... that's dumb! I was still developing on D10.2, and the "add field" button is broken on D10.3+.

Also, we don't have browser tests for the UI yet. We should, but realistically... that's not on the radar yet.

(A switch() was replaced by map() in EntityDisplayFormBase::multistepAjax(), which apparently means it cannot handle unknown values == any buttons that the Core code doesn't know about, anymore. Fine; I won't call parent::multistepAjax().)

Creating MR, but I might merge this myself. Unless someone prods me, that may wait until Monday morning, while I try to get some other fixes in a 3.0.1 release.
