Buttons in accordion inherit wrong box-sizing #1204
Description
I'm not really sure how inheritance works in the browser here, but due to the * {box-sizing: inherit;} rule, all the content inside a DB Accordion gets box-sizing: content-box (from the details element default value, apparently). Because .elm-button has a min-height of 2.75rem and padding, this causes them to grow beyond their normal size inside an accordion (because content-box means padding gets added to the height).
Setting box-sizing: border-box on the details tag does not solve this issue. It only gets inherited into the button if it's set on a wrapping container (div).
