Why does a vertical VDivider disappear when in a VItemGroup?

[angrymarker]

I'm sure if I was more familiar with CSS I would be able to answer my own question. I am using a VItemGroup in lieu of a VChipGroup and noticed the vertical VDivider doesn't appear in the VItemGroup, but does in the VChipGroup. Wondering if there's a way to get it to show.
