Running the code on www.rust-lang.org doesn't work

[XrXr]

Go to www.rust-lang.org and click on run, it will show Running... forever.

Looking at Chrome's console, this seems to be an issue with www.rust-lang.org served over HTTP instead of HTTPS like play.rust-lang.org.

XMLHttpRequest cannot load http://play.rust-lang.org/evaluate.json. The request was redirected to 'https://play.rust-lang.org/evaluate.json', which is disallowed for cross-origin requests that require preflight. (index):377 Uncaught TypeError: Cannot read property 'split' of null
