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

**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.

**Steps to reproduce**

1. Trigger Signature batch / queue
2. Reject
3. Trigger any other signature

**Error messages or log output**

```shell

```

**Detection stage**

In production (default)

**Version**

7.40.0

**Build type**

None

**Device**

iPhone 15, Samsung S24 Ultra

**Operating system**

Android, iOS

The payload names no files or tests. First reproduce the queued or batched signature rejection on the listed iPhone and Android devices, then trace the pending-request state after rejection. Done means rejecting the batch leaves no stale request or approval, and a subsequent signature can be initiated without reinstalling the app.
