13086	[Patch] Detect all self-intersecting ways (multipolygons, less common tags, etc.)	naoliv	team	"While searching for objects with invalid geometries (using `ST_IsValid()` with a database) I saw that some objects aren't reported as wrong/invalid in JOSM.

For example, validating the attached file in JOSM nothing is displayed, while I can see a `Self-intersection at or near point -49.642125 -21.152750000000001` from `ST_IsValid()`

Search for `problem=yes` in the attached file and you should see the intersection.

Shouldn't JOSM catch intersections like this?
