Parent loader is not invalidated

[v-morlock]

Description
The form data of the parent layout is not invalidated when saving and redirecting back to the parent. My app is structured like this:

• +layout.svelte
• +layout.server.ts
• +page.svelte
• /subpage/+page.svelte
• /subpage/+page.ts
• /subpage/+page.server.ts

When submitting a superform on /subpage/+page.svelte, data is being saved to the database and a redirect back to /+page.svelte is triggered by

			return redirect(303, "<url>");

My superforms instance in /subpage/+page.svelte is configured like this:

	let superform = superForm(data.form, {
		validators: zodClient(baseArticleSchema),
		dataType: 'json',
		resetForm: false,
		invalidateAll: 'force',
		applyAction: true,
		onError(event: unknown) {
			console.error(event);
		},
	});

and additionally, i've enabled SUPERFORMS_LEGACY: true. When submitting the form, the navigation back to the main page works as expected, but the parent data from the layout-loader is only invalidated like every second time.

If applicable, a MRE
Let me know if you need a MRE, but maybe it's something obvious so just let me know please :)

A MRE would be useful for this!
