Django 1.5 bug with template "extends"?

Question

I'm trying to figure out what is wrong with my code. As far as I can tell it may be a bug with Django 1.5. I am running on windows. The templates, css, etc.. are being found no problem. Semantically everything is being outputted to source correctly. The problem is some sort of quirk when the browser renders the page, possibly a development server quirk.

The issue is very difficult to explain so I made a video and put it on YouTube. The quirk only occurs if the the template has an "extends" in it.

As you say in the comments, the problem is with chrome as far as I know the Inspect Web code is different from the View Source code, a blog's post about this, maybe this can happen because a chrome's bug or I do not know if Jquery makes and inject or something like this, I do not think that this is a django's bug. So i think that you do not have to worry of all about this.
