Previously, we'd only have calculated sorted fingerprint blocks once,
but not after setting a new fingerprint.  We never ran into this bug,

future uses of that setter would have caused trouble.

Found while writing Javadoc comments for #19613.

Resolve very few of these warnings by suppressing them, in particular
getters and setters that happen to contain more than 2 lines of code,
because we should either document all or none of them.
