Reactivity / store regression in 3.39.0

[fbasso]

Describe the bug

Hi !

I noticed a regression from the 3.38.3 to the 3.39.0. When a store is defined inside an object, and given to a child component, this one is undefined if used with the $ sign in the script section.

See the simple REPL for a better explanation 😃

Thanks !

Reproduction

You can reproduce the issue in this REPL : https://svelte.dev/repl/dcceadde29ce439886ffff8260f331a6?version=3.39.0

As you can see on the display, Inner store is undefined. This is due to the line

$: console.log('Inner store', $store);

in Child.svelte.

Commenting this line, and the example works again. It works with the 3.38.3.
