on("accountsChanged") not firing

Nobody has claimed this yet.

An application may request accounts from the user using the `eth_requestAccounts` RPC method.

The user may refresh this page, leaving a pending account request on MetaMask.

When the user later finishes accepting this account request, the `accountsChanged` event does not trigger on the page.

Therefore, there is no way of determining if the user has accepted an account request after a page reload has occurred in-between.

Temporary solution which should work: Poll the `eth_accounts` RPC method every few seconds and if an account appears then it is clear that the user has accepted the account request. This method does not allow you to detect if account request denied.

I assume the purpose of event handlers is to avoid polling like this, so I hope that the event logic gets changed.

Start by reproducing the sequence involving eth_requestAccounts, a page refresh, and later completion of the pending request. Trace the implementation of the accountsChanged event and verify that it fires after the request is accepted following a reload, rather than requiring polling eth_accounts.
