Each eth_requestAccounts or personal_sign call opened another approval window, so a page calling in a loop could cover the screen with identical prompts. While a site's connection or signature prompt is unanswered, a further request of that kind from the same site is now refused with EIP-1193 -32002 and opens no window; all signing methods count as one kind. A connection prompt whose toolbar popup closed before it connected, and which the toolbar popup no longer opens, is shown again by the site's next request instead of refusing the site until the address changes.
