Flex container and determining auto basis size

I have a flex view with some embedded views inside an embedded flex container. One of the Views has a column container in it which changes to stacked layout for mobile widths. I want to display all of this embedded view at any width, no scrollbars, so I thought I should set the basis for it to auto, however now it’s becoming too tall…

How can I make the gap at the bottom, below the column container, go away (the red X space)?
The column container basis is set to auto and grow/shrink are set to 0

I’m also having trouble with this, have you found a fix?

If you make the default height of the view shorter than needed (for example 10px) then it should work correctly with a basis of auto on the embedded view that its in.

This is probably a bug, but that’s the workaround I know of, often times I set a binding on defaultHeight to be something like 600 if the device is the designer, else 10
