Start by reproducing the failed transaction flow using the listed nonce-editing steps in Chrome on macOS, then trace the confirmation flow and its toast handling in the TypeScript extension code. Done means a failed transaction displays a toast before or alongside the return to the Home page, matching the existing success notification behavior.
