Jonathan is right and I was wrong. There is no kerning pair between
\emph{V} and comma and this is not a bug in the font design, but an
unfortunate combination.

My personal opinion on this concrete rule is only emphasize the
expressions that need to be emphasized. In "\emph{KrV}," KrV is an
acronym-abbreviation for a work (the German original of the “Critique of
Pure Reason”) and the comma separates a different concept (like page
number). But this has the collateral effect of unwanted spacing.

I hope it helps,
