10631	Filling in inner parts with the outer area doesn't work as expected	Grillo	team	"What steps will reproduce the problem?
 1. Draw a multipolygon
 2. Try to expand the outer part into the inner part by drawing a separate polygon and connecting it to the outer part
 3. join the inner area with the newly drawn polygon with ctrl-j

What is the expected result?

In earlier versions of Josm the outer would fill into the inner, and the inner border would move to the extent of the new placement.

What happens instead?

If the expansion polygon ends at the old outer border and it's joined with the inner part, it just disappears. If it continues into the outer part, the inner grows into the outer part (tags of the new area will also be placed on the inner part, but that's irrelevant to this ticket)

Please provide any additional information below. Attach a screenshot if possible.
