Describe the bug
I am trying to debug an $effect block using $inspect.trace, but the output gives me a no context for the various $derived and $state nodes in the tree.

I see in a simple playground example that it typically prints the value of the dependent variable inline. Is there an easy to understand reason why I am not seeing the same locally?
Playground example: https://svelte.dev/playground/16348415b1a44cb1b2390885c204f677?version=5.30.2
Reproduction
I can't repro using the playground, but I am using the same version as the playground: 5.30.2

In the CreatedAtError you should see the stacktrace that lead you back to the place where the derived/state was declared
