Issue with multiple videos in same container

Problem/Motivation

When having multiple videos in the same container, and beore accepting cookies, it's always the link of the first videos that is displayed.

Steps to reproduce

Consider this

<p>
  <iframe frameborder="0" height="315" src="https://www.youtube.com/embed/xxxxxxxxx" title="YouTube video player" width="560">&amp;#13;&amp;#13;
  </iframe>
  <iframe frameborder="0" height="315" src="https://www.youtube.com/embed/yyyyyyyyy" title="YouTube video player" width="560">&amp;#13;&amp;#13;
  </iframe>
</p>

We have then 2 blocks, but both show the same link: https://www.youtube.com/embed/xxxxxxxxx
