Hmmm, that's strange because I have done a number of tests WITH dragged content using this template and it works just fine across all browsers and all OS systems for me.
Here is an example with the graphic, text and Pull Quote all being rich content dragged unto to the stage and centering just fine.

I tried to "break" it but everything seems to work out just fine. Can you test this template out and see if you can get dragged content NOT to be relative-positioned? I couldn't.
Thanks for your time on this. I really appreciate it.
