shoals not rendered in nautical map style

[quantenschaum]

Description

Neither natural=shoal nor seamark:sea_area:category=shoal tagged polygons are rendered when using nautical map style. Shoals are very important to navigation, so I consider this a bug. natural=shoal is rendered in the non-nautical map styles, though.

natural=reef is rendered, but it does seem to use the same shader for all values of reef. Reefs and other features also may get hidden below other polygons like wetland/tidalflat, see #17835.

How to reproduce

• look at https://map.openseamap.org/?zoom=15&lon=12.95511&lat=52.33529 (use live updates)
• compare to openseamap web view
• switch between nautical and osmand map style and compare

Actual result

• shoals rendered with osmand style
• nothing with nautical style (reef is shown, but not as sand reef)
• seamark:sea_area:category=shoal not shown at all

Expected result

• outline for seamark:sea_area:category=shoal
• area for natural=shoal respecting surface key

shoal occurs in the topo render style, but shoals not rendered in the topo style. Why?

[quantenschaum]

seamark:sea_area:category does not seem to be in the OBF.

Steps to reproduce

• Download Germany Brandenburg, Berlin map
• Enable live updates for Germany Brandenburg, Berlin map, download them
• Go to 52.33529 12.95511
• See actual result in default (OsmAnd) map style and compare it with Nautical map style
• Situation is the same, if in Nautical map style in Configure map > all seabed detail option is enabled

Actual result:

• Shoals introduced by live updates can be observed in default (OsmAnd) map style and at the same time they are not seen in Nautical map style
  Shoal 1 on OSM, Shoal 2 OSM
