Flexbox

Describe the bug of the extension

Leaving the "occupy maximum width" or "occupy maximum height" on multiple flex items inside the same flex container causes each of the items to resize to the full width/height of the container, and when both are turned on for multiple flex items, they all assume the full size of the container and push each other out of the container.

Steps to reproduce

1. Add a sprite with the FlexContainer behaviour attached to it.
2. Add an instance of the sprite to the scene
3. Add two or more other sprites and attach the FlexItem behaviour to them.
4. Add an instance of each of these objects to the scene
5. Check both "Occupy maximum width" and "Occupy maximum height" in the behaviour properties for both the Flex Items
6. Run a preview

Thank you for reporting an issue. The main maintainer of this extension probably won't make any update. Have you consider using the Anchor behavior instead?
