Pictures do not appear in Safari’s Reader View

I am starting to use the Wrap Text feature in Sparkle, e.g. the big picture on this page uses “Above and Below” wrap text option:

However, if I use Safari’s Reader View feature, the picture does not appear. Is there a workaround?

Unfortunately reader view uses an undocumented heuristic to pick what goes in the view and what doesn’t… I have no idea I’m sorry.
