Dead space in accordion block when all sections closed (only on desktop)?

Working with an accordion that has a background/ first item expanded / not allowing multiple open items. The issue is that when all items are minimized, there's dead space at the bottom (or top, or top and bottom, depending on how the block is aligned). This issue only occurs in desktop view when "expand first item" is checked (not an issue on mobile). Looking for code or ideas to either a.) shrink accordion to original size when all items are closed on desktop OR b.) force the accordion to always have one item expanded.

Thanks in advance!

You can't really get around this if you have the option for first item open selected. When you're editing the page the minimum height of the block is set at as many rows as it is currently taking up and won't go smaller than that minimum. If you want the minimum height to be smaller then you'll have to uncheck that option.

I would think that the likelihood of a user minimizing all of the accordion items is pretty low.
