The recent work on the review request infobox missed updating the

background color for the summary area when there weren't any issues or

Ship Its. This was showing up as white on bright grey.
We now use a much more appropriate background color, a dark grey, a

shade or two lighter than the background of the infobox itself. This is

far more readable and better fits the UI.

Tested the infobox in light and dark modes, with and without Ship Its and

open issues.
