[Bug]: Can't handler account change

### Describe the bug

Metamask is not able to detect account switching to the same website if the account is not connected.
That is, the value:
**window.ethereum.selectedAddress**
always maintains the last connected account
Which produces that I cannot update the value of the address in the events of the contracts to obtain
The same behavior can be observed for example in uniswap

I have two accounts, one connected and the other not, I change the account in metamask and the application after updating the page keeps the previous connected account and returns the values of the other account, not the current one

### Steps to reproduce

1. Two accounts
2. Left one of the two account conected to website
3. Change to another account without connected
4. The selectedAddress has not been changed

### Additional context

_No response_

Start by reproducing the account-switching flow with window.ethereum.selectedAddress: connect one account, switch to an unconnected account, and reload the site. Trace how the extension exposes the selected account and determine what behavior should make the value reflect the current account; done means the reported address updates reliably in this scenario.
