{#await then} not working properly with slot props

[aradalvand]

Describe the bug

In the following example, the physicalWidth inside the {#await} block isn't updated (see the REPL linked below).

<Wrapper let:physicalWidth>
    {physicalWidth}
    {#await getWhatever() then result}
        {physicalWidth}
    {/await}
</Wrapper>

I think if you pass physicalWidth to the function returning the promise then it updates, but I'm unsure if thats what you are going for here, but checkout https://svelte.dev/repl/6d5de4c31a2445f7b3f67e04af0e55b9?version=4.1.1 might be a potential workaround to what you are trying to do

That doesn't change the fact that my original example showcases a bug.

but checkout https://svelte.dev/repl/6d5de4c31a2445f7b3f67e04af0e55b9?version=4.1.1 might be a potential workaround to what you are trying to do

I'm not really asking for a workaround, I'm just reporting a bug.
