Google Sites – Chrome Doesn’t Display URL Gadgets

gadgetgoogle-chromegoogle-sitesurl

I own a Google Apps domain, and I've built a site in Google Sites. Within the site I've embedded some gadgets, added by URL.

The problem occurs when I open the site in Chrome: the gadgets aren't displayed and there's a white space instead of them. This doesn't happen when opening the site in Firefox.

Here's the difference. This is the page as displayed in Firefox:

page with gadgets dispalyed

This is the page from Google Chrome, instead (without the gadgets):

How can I prevent this behavior? I'm aware that the gadgets loaded by an external URL can be seen as non-secure items, but why is Chrome blocking them at all?

The problem is due to the new security rules adopted in Chrome 21. URLs in the source code must use HTTPS instead of HTTP, as stated here.
