Using `await` with `@const` inside shadcn sidebar causing every element to be doubled

[henrykrinkle01]

Describe the bug

Before this, I used const foo = $derived(await getFoo()); in the script tag. However, this causes every dropdown elements to not function. In an attempt to fix the issue, I move it down to the markup section using @const and now everything is displayed twice. It seems one version is from SSR and non-interactive and the other is from hydration.
