Css style fix problem. But that does not mean it's not a problem.
for example I didn't realize in the development status, because there was no problem in 10-15 pages.

In fact, as the number of pages increases, many css comments seem to tend to mislead.
In fact, as the number of pages increases, few css renderer seem to tend to wrong. I try to report them as possible.

Over to dgrogan for further triage.

Tested the issue on chrome reported version 64.0.3282.186 using windows-7 with steps mentioned below:
1) Launched chrome reported version, dragged and dropped the bugs.html file in to browser
2) Clicked on Ctrl+p, and scrolled the page down
3) Didn't observed any multiple headers.
