`field.value()` doesn't reactively update after calling `field.set(...)`

[teemingc]

Describe the bug

When using the form remote function, calling form.fields.field.set(...) doesn't cause form.fields.field.value() to reactively return a new value.

Reproduction

https://stackblitz.com/edit/sveltejs-kit-template-default-cfztyihe?file=src%2Froutes%2F%2Bpage.svelte

Press the button to call field.set(...) and see that the value isn't updated reactively unless we create a $state and set it ourselves.

annoyance

Additional Information

I need to programatically set the value when using custom selects from shadcn-svelte. The value needs to be reflected in the trigger element text which is a button.
