Firefox/Mac's doesn't vertical align the text of widgets correctly with the current combinations of line-height. There seems to actually be a miscalculation in Chrome rendering the line-height: 15px versus line-height: 16px in Firefox.
Chrome/Mac | Firefox/Mac with sans-serif
As comparison Firefox 51/Win:
| Subject | Repo | Branch | Lines +/- | |

| MediaWiki theme: Align “framed” ButtonWidgets cross-browser | oojs/ui | master | +12 -6 |
I must have been in a fever dream when I thought I found the reason for this. Meant to find fallback font as root of that problem in my tests. Can't reproduce that assumption though.

@Volker_E , is this causing the problem caught at https://drive.google.com/open?id=0B0TFyNZz_0j9SW5VNVZ3SnZmZzQ (first button slightly smaller than the big Save one)?
@Etonkovidova It'd be great to have your help on comparing the proposed patch across browsers/platforms.
