MINGW-packages: libxmlsec1 static linking error

I have a couple of programs which link statically to libxml2. The first works fine. The second also uses libxmlsec1 but fails to link because it seems that libxmlsec1.a and libxmlsec1-openssl.a have been linked dynamically against libxml2.

Is this is a similar issue to: https://github.com/Alexpux/MINGW-packages/issues/3538#issuecomment-408016158? (where I temporarily fixed that by rebuilding using --without-nghttp2).
