bug: Persisted state doesn't update `.current` state in runes mode

[ieedan]

Describe the bug

Just spent a lot more time than I am proud of trying to figure this out.

Earlier this morning I noticed that #225 and the subsequent release broke one of my selects in my application. I have since been trying to reproduce.

After a while I figured out that this bug for whatever reason only occurs in runes mode.

Basically the storage would update but the value of .current would not.

In other words this works:

<script lang="ts">  
    import Counter from "./counter.svelte";
    import { PersistedState } from 'runed'

    const count = new PersistedState<number>('count', 0);
</script>

<Counter bind:count={count.current}/>

This doesn't work:

<svelte:options runes/>

<script lang="ts">  
    import Counter from "./counter.svelte";
    import { PersistedState } from 'runed'

    const count = new PersistedState<number>('count', 0);
</script>

<Counter bind:count={count.current}/>

Severity

annoyance

So with some more investigation this has nothing to do with $state but more to do with legacy/runes mode

I get the same results when just adding blank $props.

I'm still not sure why this is the case...
