This ignore a Suspense boundary from the timeline when it has no visual representation. No rect. In effect, this is not blocking the user experience.
Technically it could be an effect that mounts which can have a side-effect which is visible.
It could also be a meta-data tag like
<title>which is visible. We could hoistables a virtual representation by giving them a virtual rect. E.g. at the top of the page. This could be added after the fact.
