问题
I am having a problem with that preview tab in network section. When HTML is returned I am seeing the raw HTML in both preview and response. Sometimes, but very rarely, I HTML is rendered properly in Preview tab.
Am I doing something wrong or it's just some Chrome bug?
Thanks

I was testing this as well. What did it for me was adding the http header.
header('HTTP/1.1 500 Internal Server Error');
Then of course some proper markup formatting. But the status code was what I needed to convince chrome to render the preview.

Problem is solved when you add a proper Content-Type header. If its text-html then it will display content like it would be normal text no matter what do you send from server. I had the same problem and solved it by force'ing output type in $.ajax options. When i changed it to application/json and its nicely formatted now.
