Using a tunnel right away?

So I have the code below.
SomeComponentThatRendersToTunnel will try to put something inside footer-tunnel but it wont show on first render. My guess is that it's because it's below what will try to put something inside it. If I move the tunnel above the component it does render.

Is this a bug or expected? Is there a way to get around it?

Reproduce the reported ordering with TunnelProvider, SomeComponentThatRendersToTunnel, and TunnelPlaceholder using the example in the issue. Inspect how the provider and placeholder handle first-render ordering; done means establishing whether this behavior is expected and identifying a supported workaround or a clearly scoped fix.
