1. Add Question to Question Group
2. Specify Text Display (doesn't have to be this question type)
3. Select 'Inset HTML5 Video' in WYSIWYG editor.
4. Click 'Browse Server'
5. Upload .mp4 video using built in KCFinder.
6. Select uploaded video
7. Select responsive width
8. Click OK.
9. Video then shows in WYSIWYG editor and plays as expected.
10. Click Save
11. Page reloads
12. Video can no longer be seen (just a yellow box around the Div when you hover over it)
13. Clicking Source only gives the following: <div class="ckeditor-html5-video" style="text-align:center;"> </div> and is missing the <video> tag that was in the 'ckeditor-html5-video' div before the page reload.

If you do the above steps as a SuperAdministrator it works perfectly as you would expect. But then log in as the standard user, go tho that question and click save on that same question, the video disappears again.
