How do I make a script run only the first time the `layout` is instantiated and not all subsequent pages (which inherit that `layout`)?

Describe the bug

In a new Svelte Kit project I have a <script context="module"> in __layout.svelte.

The load function in it is called on each page I change.

I thought instead it was only called when the layout is instantiated for the first time.

I’m doing it wrong?

If onMount only runs once I would definitely not expect load to run more than once. Just my 2 cents though.

The way it works feels backwards to me. I wouldn’t expect the layout to be re-mounted when I change pages - I guess that’s the case?
