In release lists (e.g. release group index or label) the text for countries and dates is slightly lower than the text of the other columns, when a flag is present.

This can be fixed in the CSS for .flag-class:

--- a/root/static/styles/flags.less
+++ b/root/static/styles/flags.less
@@ -1,6 +1,6 @@
{{ .flag-class (@image) {}}
{{ background: data-uri(@image) no-repeat left center;}}
- padding: 3px 0 0 19px;
+ padding: 0 0 0 19px;
{{ }}}

I didn't see any downside when adding this fix
