True, but wblink doesn't work in Bakery full descriptions or in show_menu2
That's correct. Some modules/snippets have a little bit too aggressive kind using htmlentities().
So you will see
[wblink123] but the real code behind is
[wblink123] which can not be evaluated by the output filter to prevent i.e. a wanted, literal
[wblink123] in a FAQ section or somewhere else.
