Gerrit review blocked on "Needs Code-Style"

Why is <https://gerrit.libreoffice.org/#/c/44418/> "Suppress 
loplugin:unnecessaryoverride..." blocked on "Needs Code-Style" (and 
which I at least cannot override via some +1 reply)?  What's going on in 
our Gerrit?

(Should that be an attempt at implementing the Gerrit-side clang-format 
enforcement:  Note that that commit, while including a new source file 
compilerplugins/clang/test/unnecessaryoverride.cxx that should be 
clang-format--enforced, also includes a fix to .clang-format necessary 
to keep that source file's Clang -verify comments intact.  Could it be 
that Gerrit checks clang-format on that source file with a stale 
.clang-format?)
