ch5-video no longer tells all ch5-background to let video through #273

TB Case#: 00198843

Since commit 95a46ec video does not show through multiple ch5-backgrounds.

Previously you fetches all ch5-background elements to tell them to let the video though.
In the mentioned commit you changed this to only let video through on a hardcoded element id (used by the shell template) and a parent ch5-background.

The issue can easily be seen on line 460 in ch5-video.ts in the new commit.

From:

private ch5BackgroundElements: HTMLCollectionOf<Ch5Background> = document.getElementsByTagName('ch5-background') as HTMLCollectionOf<Ch5Background>;

To:

private shellCh5Background: Ch5Background | null = document.getElementById('template-content-background') as Ch5Background;
private parentCh5Background: Ch5Background | null = null;

We really need the video to be able to go through multiple ch5-backgrounds.
