I go a little further and use distinct Chrome profiles for every project to avoid this. It also helps to keep saved credentials for e.g. client-specific SaaS accounts separate without commingling them with my own 1Password vault.

*I know 1Password now supports multiple vaults, but I haven't had a chance to try that workflow yet.
