Describe the bug
Changing the "Header Size" style of a container changes the corner rounding, and removes it completely when "Header Size" is set to 0

To Reproduce
Steps to reproduce the behavior:

1. New or existing document
2. Bring out General->Container
3. Check the "Rounded" checkbox for Container (No rounding)
4. Bring out General->Vertical Container
5. Check the "Rounded" checkbox for Container (Has rounding)
6. Change the Header Size of the Vertical Container to 0 and you'll see the rounding disappear

Expected behavior
I would expect for the rounding to not be influenced by the header size.

If I'm reading this correctly, the issue is, when you change the size of the header to 0, the rounding disappears, correct?
I'm really annoyed with this as well, if that what you meant.
I want to be able to create a rounded "table" without a header, and just have 3 cells in a row containing text in them.
