Jacques Lucke 152f5dc897 Fix #111633: crash with cyclic node tree zones
The problem was that there was a cyclic nesting dependency that was not detected
correctly, which led to problems further down the line. See the PR for details.

Right now, the zones just disappear when there is an error. This has to be improved
at some point, but it outside of the scope of this patch.

A regression test that covers this case is added as well.
