**Short description of error**
Making full copy of a scene mess up enabled/disabled flags for collections in an unpredictable manner.
**Exact steps for others to reproduce the error**
Open the file.
2nd and 3rd collections are disabled and all of them are collapsed.
Make full copy.
Now only 3rd collection is disabled and all of them are expanded.
