Disable Chrome stripping subdomains from URL

In version 69 of Chromium and Google Chrome default browser behavior is to enable “Omnibox UI Hide Steady-State URL Scheme and Trivial Subdomain” feature.

This will cause browser not displaying not just the protocol part of address but also what it considers trivial subdomains.
Subdomains like www or m subdomain will not be shown in address bar with this feature enabled.
This will cause www.example.com to be shown as example.com and www.m.example.www.example.com would be shown as example.example.com, like described in this issue report:


To disable this feature open chrome://flags/#omnibox-ui-hide-steady-state-url-scheme-and-subdomains in your browser and set the flag to “Disabled”.

Version 69 has also introduced new UI design.

If you wish to revert to old design you can do so with “UI Layout for the browser’s top chrome” setting.
Input chrome://flags/#top-chrome-md in Chrome and set it to Normal to have the old UI design again.
