Hidden Accounts Drop-Menu Persistence Issue After Deleting Accounts

### What is this about?

After hiding an account, a 'Hidden accounts' drop-menu appears in the account list. When attempting to delete a hidden account while in the hidden state, the 'Hidden accounts' drop-menu persists and remains visible instead of disappearing as expected.


Reproduce the account-list flow by hiding an account, opening the Hidden accounts menu, and deleting the hidden account while that state is active. Trace the account-list state that controls the menu, and consider the issue done when the menu disappears after the last hidden account is deleted.
