Card height not automaticly adjusted on the button card.

[RVO25]

Describe the bug
I'm using a single card to creates toggle 3 different entities with just 1 card. (like the Lovelace entities card). I created a button card (with the type text) with a sub-button group. In that sub-button group, I created 3 new buttons that I want to have stacked vertically.

But when I add more buttons in the group, it doesn't extent the height of the card. (See picture) I have to manually adjust this in the deprecated layout settings.

The entire card is placed inside a section of a popup.

I have tried to remove the height set by default to make it autogenerate again but that doesn't do anything.
