Content passed through multiple slots behaves unexpectedly

Describe the bug

When a value is instantiated on a +page.svelte file and passed through multiple slots, it behaves unexpectedly.

In this example reproduction, I have a counter component that loops through an array of values by simply incrementing the index. The currentValue and the index are bound so they can be referenced externally.

The bound variables are then passed through for observation in two different ways, and the combination of slots causes ONE of the values to no longer update, but one continues to update correctly.
