Whatever blocks the synchronous reference also blocks the parent from resolving.
In practice the server doesn't outline anything that isn't already there so it would be rare but for client references the chunk dependency can show up like this.
This surfaces some other issue with DevTools not properly surfacing this that I'm still investigating.The issue is that these get modeled as the last debug info on the fiber which we typically consider blocking the parent Server Component or in general parent component. E.g. promise in child position of a Server Component is blocking that Server Component. So it becomes more like the parent component was awaiting the reference rather than that the<div>itself was suspended on it which isn't exactly wrong. Regardless, it properly bubbles up to the nearest Suspense as expected.
