In Hubbub, the "has_children" tree callback is never used.
It is defined in hubbub\include\hubbub\tree.h, line 286.With that line commented out, Hubbub still compiles fine and tests pass without error.
Hence I believe that the "has_children" callback could (and should?) be removed from the hubbub_tree_handler.
What do NetSurf developers think? Ralf
