No-JavaScript feature seems to not work

I am not able to verify that Virtualmin will automatically detect that JavaScript is not available and function correctly. (Some of the advertising copy seems to make this claim.)

I switched off JavaScript in Opera, then went to the demo site at and logged in as the demo user "demodomain" with password "demo".

Many of the links are nonfunctional. The JavaScript menus activated by clicking on the + sign at the left margin are nonfunctional. The following items seem to be links, as judged by the cursor shape, but clicking on them causes no effect:

Server Configuration
Backup and Restore
Logs and Reports
Webmin Modules
