Svelecte mutates values passed without bind

[jamesst20]

Error

[svelte] ownership_invalid_mutation node_modules/.pnpm/svelecte@5.0.0-next.4_svelte@5.0.0-
next.135/node_modules/svelecte/dist/Svelecte.svelte mutated a value owned by ...FormSelectBuilder.svelte. 
This is strongly discouraged. Consider passing values to child components with `bind:`, or use a callback instead

Demo

I have a component that can build options passed to Svelecte.

Sample code

<FormSelectBuilder bind:value={field.choices} multiple={!!field.multiple} />
<FormSelect
        bind:value={field.choicesDefault}
        options={field.choices}
        label={"Default value(s)"}
        multiple={field.multiple}
      />
 <FormToggle bind:value={field.multiple} label={"Multiple"} />

Problem

It seems that as soon as I select an item in Svelecte (FormSelect), Svelecte mutates the field.choices[i] I have selected.

I believe this happens because it sets $selected: true to that option.
