For a simple template which simply embeds and image I encountered the following strange behaviour.
When entering VE the puzzle icon is placed where the image is normally situated pushing that image downwards. Since the template is used in lists and since displacing the image does not increase the line hight the results are a bit weird as can be seen in the example below.
- Make the puzzle-icon not appear (it doesn't appear for all templates but I could find no documentation on what triggers it's appearance).
- Force line hight to be increased by the height of the puzzle-icon (while the end result will still look weird you won't have images overlapping each other.
