• Seems to be a conflict with the dimensions of parent and child container.
• Don’t think it needs to be fixed. Better to remove the problem.
• The most clear and efficient solution would be to just uncover/cover the content, similar to how the close transition is defined but without fade effect.
• We should design a standardized pattern for this. Similar need in main navigation, and surely in other places too.
