W0307: Two components keeping one URL parameter

A component's field marked @ui.URL("page") is kept in the page's ?page= parameter. Two instances of it on one page keep the same parameter: each fills from the other's value, and an event in one writes over the other's. A urlKey on a tag keeps that instance's parameters under a name of its own, ?requests.page=. Reported by vukavet for the components one markup renders, by type, with or without the same urlKey.

<main>
  <Table title="Requests" />
  <Table title="Users" />
</main>
