19526	Multipolygon validation failures	pch14@…	pch14@…	"Two cases, where validation does not catch errors in multipolygons from uploading.
Screenshots and OSM file to be attached.

1) Move a node from an inner ring outside of the outer ring
2) Make a section of the inner ring also part of the outer ring

Both times, trying to upload will not display a warning or an error.
Neither will starting validation do so, when nothing is selected at all.

The Error will only show, when starting validation and the relation itself selected.
In case two, this only after having downloaded the missing members thereof.

The error messages differ
1) Intersection between multipolygon ways
2) Multipolygon outer way shares segment with other ring"	defect	closed	normal	20.07	Core validator		fixed
