depends() stops working as expected after form submission

[themajashurka]

Describe the bug

Registering a custom dependency with depends('load:child') within a page's load function, and calling invalidate('load:child') with setInterval in the sibling +page.svelte in order to mimic a single polling behaviour, causes +layout.server's load function to be called as well after submitting form on same page.

Reproduction

https://github.com/themajashurka/depends-repro

Go to /child. You should see periodic logs on server about child load function being called.
Submit form. Now layout load function is called too.

Hi,
this seems to happen because the enhance-action calls invalidateAll.

invalidate_all sets force_invalidation to true, which causes all following invalidate calls to invalidate everything.

Similar behavior is described in #10677.
