Abort Stale Invalidation Request

[john-michael-murphy]

Describe the problem

Consider the scenario where several invalidate requests to the same dependency are triggered in rapid succession (say because of an updating query parameter, e.g. ?search=foo).

The order in which these requests return from the server is not guaranteed, which means it's possible that the last resolving revalidation will be stale.

Describe the proposed solution

I wonder if we allow an optional abort signal, where AbortSignal implements the canonical Abort API.

function invalidate(
  dependency: string | ((href: string) => boolean)
  options?: { signal?: AbortSignal } 
): Promise<void>;

Alternatives considered

Sveltekit's invalidate function could manage this automatically, but I worry there are scenarios where one might need multiple inflight invalidation requests.
