You can observe this problem by opening this in a new private tab:
https://app.element.io/#/room/#matrix:matrix.org

This is a public room with guest access enabled and Element will use a
guest account to display it.

Showing a "Forget room" button in the header for guest users is
pointless. Clicking on it leads to a `M_GUEST_ACCESS_FORBIDDEN` error.
