Get rid of those 2 vees of space after the "Synopsis" section heading.
This is a regression in _groff_ 1.23.0 relative to 1.22.4, so setting severity
to important.
(The reduced quantity of blank lines after the page header and before the page
footer was a deliberate change for continuous rendering mode.)
