The spacing around on all sides should match.

The spacing on the Multi-select has similar spacing issues.

The desired result is for all the spacing within the input to be 8px. 8px at the top, left, and bottom edges of the input container, and 8px between options, vertically and horizontally. Not sure what combination of padding and margin it will take to get there, but this is visually what the user should see.
