amenity=language_school doesn't render on osm.org

[edison23]

Expected behavior

Nodes with amenity=language_school render on osm.org with a school icon (or at least as generic nodes with the school's name).

Actual behavior

The nodes tagged as amenity=language_school don't render at all. The only way to find them is either search, or features query if you know exactly where the school is. Examples of language school nodes:

Thanks for the suggestion.

We currently render amenity=school with a name label and with a color fill in case it is tagged on a non-building polygon - see: https://imagico.de/map/styleinfo/#style=osmcarto&section=tags&key=amenity&value=school.

We do not render amenity=language_school at the moment.

Currently 7259 uses, 6k on nodes, quite a large percentage with language:<code>=* - this could be used in visualization.
