Chrome extension not always using TouchID

I have the 1Password Chrome extension installed, and when I unlock my vault by clicking on the 1Password icon in the toolbar, it always prompts me for my password first. If I click the icon again to make the login window disappear, then click it again to make it reappear, it lets me log in using Touch ID. I always have to go through this multiple-click process to get the Touch ID prompt. I've tried both the standard 1Password Chrome plugin and the beta plugin, and I receive the same behavior from both. I've also tried restarting the browser and restarting my computer.

When I open the 1Password Mac app, it always prompts for Touch ID first (unless the 30-day window between password logins has lapsed). So, the problem seems isolated to the Chrome extension. Any suggestions?
