Possible wrong "Style for outer way mismatches"

[naoliv]

I don't know if it's related with #10227 but download this relation ​https://www.openstreetmap.org/relation/303650 and validate it.

It's possible to see some "Style for outer way mismatches" warnings.
Or I also can't see what is wrong here or the test is giving a false positive.

It is complaining because some islands are tagged leisure=nature_reserve and others are not. JOSM thinks this is an old fashioned multipolygon with tags on the outer ways. In this case, the tags relevant for the area must match for all outer ways. This is not the case in this example.

A fix would be to skip the check for old style multipolygons unless the relation has exactly one tag, namely type=multipolygon.

[naoliv]

Could the validator message be clearer about this? Maybe also displaying the tag that it is finding suspicious.
I don't care about the warning itself, but I would like to have a better explanation, if possible.

Ticket #10549 has been marked as a duplicate of this ticket.

[Don-vip]

Looks like this ticket must be addressed while fixing #10529.

I can't access JOSM ATM, but that is a type=boundary relation and always has been. Why does it complain about mismatching styles at all?

[mkoniecz]

type=boundary is for some reason considered as multipolygon by validator - see #10158

[stoecker]

Replying to mkoniecz:

type=boundary is for some reason considered as multipolygon by validator - see #10158

Which is ok for completeness and everything related to geometry, but not for the style checks.

[stoecker]

In 7583/josm:

fix #10255 - don't issue style warnings for boundaries

Replying to stoecker:

fix #10255 - don't issue style warnings for boundaries

This does not solve #10549. See bastiK's comment.
