Broken tubes have a floating part when not between connecting nodes.

Yes, when they are broken they look broken.

The only time this 'floaty part' is visible is in your example situation. When the tube is between other connecting faces, there is nothing irregular.

I suggest: closing and "won't fix"

afaik there is genuine reason to have broken tubes connected like this, that being automatic item dropping (as in dispensers but dropping as soon as entered)
