DOCTYPE is always removed

After minifying it always removes from top of html content that cause the Google Chrome to load all content as body.

Loading all content in Body leads to many errors by Angular JS Lazy Loader. Fix it

Start by locating the HTML minification entry point and reproducing the issue with content beginning with . Trace where the doctype is removed and verify that minified output preserves it so Chrome does not treat the document as body content; add or run a focused regression check if the project provides one.
