I have a very weird problem, I have a markup, which is being treated by chrome (tested on mac, windows, and ubuntu-chromium) in weird manner..
I’ve created a simple version of the situation..
<h3>First Part<span>Content in Span</span></h3>
Chrome is adding extra quotes to First Part, while its not present in any other browser (tested on Firefox, and ie.)
Simple demo I’ve created on JsFiddle here..
In Chrome:

In Firefox:

This is just the way that chrome presents the text node content in the element inspector. You can see white-space better this way. The quotes are purely virtual.
