 This is a continuation of the discussion started in #42101.

 In Firefox, there is no spacing between rows in the Gallery widget. We
 want to add even spacing, without increasing the spacing in other
 browsers. A CSS expert would be great for this one :)

 For more context, see this Slack conversation:

 Also see attached screenshots for what it currently looks like in Firefox,
 and what it should ideally look like.
