Bug: Component is not a function when using Suspense and forwardRef about react

This patch solves it:

A line like this exists in updateForwardRef, but doesn't seem to exist in the replay suspense logic.

react/packages/react-reconciler/src/ReactFiberBeginWork.js

Line 415 in 480aa77

const render = Component.render;

@acdlite tagging you because I think the reconciler and suspense is your field of expertise. Happy to help with anything that can help solve this.

Ah yeah that's a good find. Want to submit a PR with a regression test? :)

[hansottowirtz]

Sure! Might need some help on how to trigger the replaySuspendedUnitOfWork function. I'll tag you in the PR.
