WIP: Fix widget visibility when multiple views

This ensure the following behavior :

• When the filter has aready been applied (most cases) :
  • if the output of the filter is hidden in the current view then the widget will also be
• When thefilter has not been applied once yet :
  • if the parent of the filter is hidden in the current view then the widgget will also be
• This keeps the former behavior correct, that is :
  • if the filter is not seleted the widget is not visible
  • the check box for the visibility obviously still show/hide the widget

Resolves: #20709
