21153	Split Object: Overlapping areas created	skyper	GerdP	"==== What steps will reproduce the problem?
1. Have a closed way or a multipolygon relation
1. Draw a new way between two nodes of the closed way completely **outside** of area, or in case of a relation with some parts outside, [attachment:josm_SplitObject_examples.osm example file]
1. Select the new unclosed way (and the relation)
1. Split Object

==== What is the expected result?
Either the split is denied or better add the outer part as a new closed way connected to the other closed way. For relations only add the former outer part to one relation

==== What happens instead?
A new closed way/relation is created as expected but additional the former outer part is added two both areas, resulting in overlapping areas.

==== Please provide any additional information below. Attach a screenshot if possible.
See #21154 for another problem with invalid result.
