Just started testing multiple variants with dynamic content in X10.

First problem, which should be easy to duplicate, is that all Javascript added to the page <head> appears multiple times, which shouldn't break the page but equally shouldn't happen.

Second is that the dynamic content, which should fill a placeholder using an AJAX call, works at desktop size but doesn't happen at mobile/tablet size. No errors are raised and the AJAX call is made corectly but then nothing.
