WebPart Zone in Page Layout not displaying

Question

I have created a new page layout using Design Manager,  two files are created, one HTML file, and the other ASPX file with the same name. You cannot edit the .aspx file directly in SPD, you can only edit the .html file. You will find in the .html all
those ASPX tags commented.
In the HTML file I added a web part zone, I copied a snippet from the design manager, right after a page content snippet. As shown below.  Saved and previewed the page with no errors.  The Page Content shows up just fine but there is
no WebPart Zone underneath it.?  Any Ideas why it is missing?
Thanks
