The Code Previews panel is initially opened in a slightly minimized state

How to reproduce:

1. Open any project
2. Create a UI Document Asset in the Project Browser and open it
3. Observe the Code Previews panel
4. Extend it by draggin the top edge upwards and then try to make it the same size as it was before

Actual results: The Code Previews panel is initially opened not extended upwards, this is clearly seen as the button to open the code preview doesn't have padding on the bottom

Expected results: The Code Previews panel is initially opened in a state that can later be minimized to as it appeared before
