 The refactored gallery block uses a nested
 `<figure><figure></figure></figure>` structure, as recommended by w3c for
 image collections.

 If a site has the use_balanceTags option set to 1, then the Gallery block
 breaks on save as  force_balance_tags restructures it from
 `<figure><figure></figure></figure>` to
 `<figure></figure><figure></figure>`.

 This is because `figure` is not listed as a directly nestable element at
