   @ueshin  Yes, it is really yes from your example, the `setitem` has behavior influence on several functions and change the final or part of behaviors for these functions (but pandas not mention this behavior change). Anyway, I will raise a issue on Pandas comunity to get the detail attitude for these beahavior changes.
