River loops are not displayed at low zoom level

[pyrog]

See :

• Doubs river near Thoraise : http://fluv.io/#12/47.1705/5.9062 (not displayed) http://fluv.io/#13/47.1704/5.9062 (Ok)
• Doubs river at Besançon : http://fluv.io/#12/47.2379/6.0246 (not displayed) http://fluv.io/#15/47.2348/6.0269 (Ok)

It seem that ways are rendered at zoom 5 to 12 and loops are not displayed. At zoom 13 to 18, areas are rendered and loops are rendered correctly.

It's seem to be a tagging problem :

• At zoom 5 to 12, the "network" is rendered :
  • Doubs river at Besançon : the loop has only a tag waterway = canal no motorboat=yes or **CEMT=***
  • Doubs river at Thoraise : the loop has tags waterway=river and boat=no but no tags motorboat=yes or **CEMT=***
• At zoom >= 13, the riverbanks are rendered : riverbanks of the Doubs are in a Relation : Cours du Doubs (1304093) wich is part of Relation : Le Doubs (156145) with tag CEMT=V

Solution : at zoom 5 to 12 draw every waterways (but a time of writing this message is see that this problem is solved :-) )
