Android Chrome may not redirect to custom URI schemes automatically

Single Sign-On authentication for the Moodle mobile app works by opening the SSO page in a browser window and trusting the browser to redirect after the login to a custom URI scheme handled by the app. Interestingly, this works when the user was already logged into Moodle in their browser, but not after completing the SSO flow. Apparently the Chrome browser sometimes won't honor an HTTP Location redirect to a custom URI scheme. In Moodle's case, the confirmed=true query parameter can be added to make the page display some nice UI with a link to proceed to the app.
