Description of the problem including expected versus actual behavior:

Steps to reproduce:

1. Create a Split chart Tile map visualization with 2 Filters Sub Aggregation
2. Move the second map: it hides the first map instead of being clipped

Turns out this was fixed in 5.0 by removing the split chart option entirely. #6001

So you just decided to let all your Kibana 4.x user with a non working system. That's a great way of managing product. Congrats.
