LastPass Authenticator Autocomplete Bug

I noticed a bug with LastPass Authenticator where the Chrome extension would autofill my username and password for the site I was viewing when I log in LastPass with my master password, but before I complete 2FA with LastPass Authenticator. I switched to alternative 2FA methods (Yubikey/Google Authenticator) because of this issue which don't have this problem.

Same Problem with FF but additional user can log on successfully

Multifactor authentication bypass

When logging into LastPass from an "untrusted" computer, the login information for a saved page populates before multifactor authentication is completed. Login to the page is possible without completing authentication.

Work Around: W/7 in FF, Start menu > All Prog > Last Pass > Vault. More clicks but works
