Waterway or water view ignores ponds with isalnds (mutlipolygons)

[InsertUser]

I know this was mentioned in the post introducing this map view, but I think it still counts as an issue even if it's low priority?

Lakes and ponds with islands are usually recorded as multipolygons with the relevant natural=water and similar tags on the relation and not on the outer way.

The lack of water tag on the outer way is causing waterway connection ro fail on lakes/ponds that are actually connected properly.

Can the processing stage be modified to copy the relation tags to the outer way(s) before evaluating connectivity?

Examples of this occurring on the map:

• Pitville Lake, Cheltenham (smaller lake to the east is correctly interpreted). Relation 6434864.
• The Mill Pond, Painswick Relation 3507735
• Unnamed lake in a park in Charlecote Relation 1834645
