Latest Chrome, 1password extension blocking the basic proxy authentication prompt

In the other thread I made with your support colleagues, I realized that likely the issue comes when 1password extension has not been fully initialized yet (clicking the extension icon does not come up with vault unlock prompt). During this time, the proxy authentication popups are blocked.
Your colleague said this conclusion has been forwarded to the team, but its helpful to put it here as well as it provides a workaround (to wait for initialization and then do proxy authentication).
