Tile Group title disappears

[Davide]

Hi,

I'm using a 2016 version of you product and I've a problem with radTileList.

I've 3 different groups with some tile for each one.

I need to drag&drop tiles from a group to another. This feature works well but when a Group is empty, his title disappears.

Also if I put a tile in it. The title remains invisible.

This behavior is also verifiable in your online demo.

Is there a way to solve it?

Thank you.
