The RPC and Blockscout "Save" buttons in Settings now set the URL inside the save, holding the lock. The save is refused if the network active when the user tapped "Save" is no longer active, on the page or in the stored record. The flash message then says that the network changed, and "Saved." is shown only for a stored URL. Before, a popup that followed a switch saved elsewhere could replace the URL before the write and still show "Saved.". It could also write the previous network's URL as the new network's.
