Svelte 5: Non-reactive behaviour for `bind:value` with wrapped components in next.222

[marianmeres]

Describe the bug

After upgrading to next.222 I'm seeing this. Downgrade to next.221 works.

// this works
<input bind:value={$value1} />

// this worked in `next.221` but stopped in `next.222`
<Field bind:value={$value2} />

Reproduction

svelte 5 preview REPL - value bbb never updates

This is a recent regression from #12843?

also encountered this issue
works correctly in runes mode though: let {value = $bindable()} = $props()
