Steps to reproduce the problem:
I use var_dumper in Laravel php framework in form of dump($var); die();, 
https://symfony.com/doc/current/components/var_dumper.htm

So when I dump any variable it returns it in form of formatted response that is raw html with styling. 

The problem is that preview tab stopped rendering html. So response tab is looking exactly the same as preview.

I have created forum thread in

https://productforums.google.com/forum/#!topic/chrome/65pep0wF9qA;context-place=forum/chrome

Which has some pictures which explain the issue.

What is the expected behavior?
The expected behavior is rendered html rather then raw in preview tab and raw in response tab. 

What went wrong?
It does not render html in preview tab.

Did this work before? Yes Can't remember which, but it definitely worked couple months ago.
