Since the last update Anki removes <object> elements in fields automatically.
Situation: I used to put <object data="11256.svg" width=150px></object> as a container for animated hanzi characters straight in de HTML box (<>) of a field. This used to work fine but since last update all existing object elements have been removed. When I add it in now and switch over to another card, switching back, the contents of the HTML box is empty.
