There's a lot of setup cost for initializing these test modules. Can we put this together with some other tests since there's only a few of test cases here?

This is not correct. It is passing the element.ref second argument. It shouldn't get the second argument in the pure case.

I didn't see that one. I'm not sure I approve. Let me think about it.

Moved the tests and branched the REACT_PURE_TYPE logic. I'm still passing the forward ref stuff for now to keep the behavior in sync with ReactDOM (#13855). Let me know if you want to change this behavior. |

Yeah we're going to revert that and change so that:

I updated on top of #13903. This now uses a slow path to implement pure in a fully recursive form. This is unfortunate but that's the easiest given the structure of the partial renderer. It doesn't make it easy to make recursive custom types. But we're rewriting this whole engine soon anyway. |
This is very slow but meh. We're rewriting this whole thing anyway.
