Fixes #36830

Hi,

The discussion #36499, brought about an interesting case after a few weeks of exploration.

Under certain circumstances, it is possible to trigger route cancellation for hash urls. Here's an exact list of steps to trigger the error: #36499 (reply in thread).

To sum up, on a two page setup, /blog and /,starting from the /blog page, go back to the / page, and click a button which looks, either like:

<button
  onClick={() => {
    router.push("#world").then(() => router.push("/blog"));
  }}
>
  to world
</button>

or

<button
  onClick={() => {
    router.push("#world");
    router.push("/blog");
  }}
>
  to world
</button>;

Would trigger an unhandled rejection, from lastRenderReject. I looked onto how this is normally cleaned, and it seems like it is not necessarily possible from the changeState method.

Adding an event listener on Router, blissfully ignored the error, and it bubbled up all the way to the console, with overlay error UI on dev mode.

I then looked at how non-hash urls handle this situation and noticed that the call to this.set is wrapped on a try/catch, and await'ed.

I replicated the same for the hash url case, and now this, doesn't trigger any errors:

<button
  onClick={() => {
    router.push("#world").then(() => router.push("/blog"));
  }}
>
  to world
</button>

While, this snippet, still triggers an error, but it is handled.

<button
  onClick={() => {
    router.push("#world");
    router.push("/blog");
  }}
>
  to world
</button>

I'll try to fill up the information down below throughout the day.

I am not sure if an integration test is warranted, nor how to go about creating one in this code base, will try to look it up as well.
