Resolves the last remaining issue in #950 (closed), i.e. Focus state on sponsors.
In Safari, the custom focus outline on sponsor images doesn't appear on focus. This PR resolves that issue. Tested in the latest versions of Safari, Firefox, and Chrome on Mac OS X 10.14.6. More details in the commit.
I still don't know the exact source of the issue, and couldn't easily reproduce it using a reduced test case codepen. I think it may be related to a combination of several styles, including text-decoration and possibly display or flex/grid layout. I may spend a little more time investigating and will update this PR if I learn more.
