[🐞] `prevUrl` of the `useLocation()` is set even if the first view.

Which component is affected?

Qwik City (routing)

Describe the bug

I have tried to detect the SPA navigation. I expected the loc.prefUrl is undefined at the first render, but it is already set to the URL of the page at the very beginning.

This is why the documentation example doesn't work: https://qwik.dev/docs/api/#going-back

[wmertens]

Good point, PR welcome. The code is most likely inside qwik-city-component.tsx

[PatrickJS]

you can use nav(-1) to go back.

the value might be set here https://github.com/QwikDev/qwik/blob/551e9fe950a469528845c43888899f1f089675d5/packages/qwik-city/src/runtime/src/qwik-city-component.tsx#L224 so PRs welcomed
