[Bug]: "Error: Request of type 'eth_sign TypedData' already pending for origin metamask.github.io" after rejecting batched Signature requests

[sleepytanya]

Describe the bug

The problem doesn't seem to arise when rejecting or dismissing standard signature requests (at least I wasn't able to reproduce the bug that way). It occurs under specific conditions, such as when batched or queued sign requests are triggered and subsequently rejected. Following this, the test dApp enters a state where initiating any type of signature becomes impossible due to an existing sign request or approval being pending.
Currently, the only workaround identified involves reinstalling the app. Reconnecting to, closing, or reloading the test dApp page does not resolve the issue.
