The above mentionned patch did paint the background of the sublabel to avoid "bold-like" effect. However the correct backgound color is the row's one, not the inset's one. To fix this, extend MetricsInfo::backgroundColor to work when no inset is specified. The code is also simplified as in master. (cherry picked from commit74540c9896) (cherry picked from commita71b96ac42)
