Prior to this commit, when using a background video on the cover of the
website_slides homepage (/slides), after saving, a traceback would
occur and the video would not be displayed.
Steps to reproduce:
- Install website_slide
- Go to /slides
- Enter edit mode
- Change the cover of the page by a video
- Save
- Traceback
The reason for that is that the cover snippet used on the homepage of
elearning is the root of an XPath instead of its own oe_structure. (This
was changed in 16.0)
[1] made it so that the style and class attributes are saved but did not
save any data attributes needed for the background-video widget to work.
This commit adds those data attributes.
