[Bug]: Pending Transactions - Popup is closed and re-opened if I confirm a transaction while having a non-EVM transaction pending

Nobody has claimed this yet.

### Describe the bug

Whenever I have a pending non-EVM transaction coming from a dapp in the MM popup, if I trigger an EVM transaction and Confirm that, the MM popup is automatically fully closed and then re-opened with the non-EVM transaction

### Expected behavior

We should not close and re-open the popup, rather keep the popup open, in the same way it happens if we Reject the EVM transaction instead of confirming it.

### Steps to reproduce

1. Go to solana test dapp https://metamask.github.io/test-dapp-solana/latest/
2. Connect
3. Trigger a Transfer SOL and see the MM popup open
4. Without confirming or rejecting, go to the test dapp
5. Trigger a regular Send/Transaction
6. Navigate to that transaction in the popup
7. Confirm the EVM transaction
8. See how the popup is fully closed and then re-opened with the non EVM transaction

### Severity

_No response_

Start by reproducing the flow with the Solana test dapp and a regular EVM transaction in the MetaMask popup, then trace the popup lifecycle when the EVM transaction is confirmed. The issue names no source files or tests; done means confirming the EVM transaction leaves the popup open with the pending non-EVM transaction, as rejection already does.
