Fixes #2127.
What?
I've fixed the bug with
mergeChildMapping
in #2047, but this fix gave birth to another bug. Before it, we actually picked an old wrapped child, but in fact we need to wrap it again. I also made changes in tests, now they assert that items are wrapped.I also picked changes from #1542 with
setSafeState
, because I need them in #1879.
