amenity=festival_grounds doesn't have the name rendered

[mikaeldui]

Expected behavior

One would expect the name of a location that get maybe a million visits per year to have its name on the map.

Actual behavior

The name isn't rendered at all.

Has about 550 area elements in the osm database.

The tag documentation lacks a language and culture independent definition of a festival and a delineation towards other tags in the domain (in particular amenity=music_venue, amenity=events_venue and amenity=theatre + theatre:type=open_air).

Practical use currently has significant concentrations in Estonia (180 uses) and southern Spain (138 uses).
