If you have `memo(forwardRef(X))`, then the inner component won't have a "rendered by" list. This is because it technically doesn't have an owner. It is artificial.

I think we should ideally set up `_debugOwner` for these Fibers in DEV just so existing tooling can find them. Or special case them in DevTools.

        const prevOffscreenState: OffscreenState | null = (current.child: any)

        primaryChildFragment.memoizedState =
          prevOffscreenState === null
            ? mountSuspenseOffscreenState(renderLanes)
            : updateSuspenseOffscreenState(prevOffscreenState, renderLanes);
