visual studio 2013 show hidden tags in design mode

In visual studio if you have an hidden field,

eg:

<div style="display:none">
   This content is not visible in design time</div>

In design mode one cannot see the content of the div.

Are there any settings in Visual Studio 2013 to make invisible tags to be seen in design mode?

i've found this:
