No, because it is not a bug, at least in so far as it is not intended
to work.  Also it only influences CMake's own testing and not other
projects so it is not public-facing behavior.

A few calls in Tests/CMakeLists.txt add

 -DCMAKE_BUILD_TYPE=\${CTEST_CONFIGURATION_TYPE}

to force building with the tested configuration but most tests do not
need this.  Most tests work in any configuration and do not depend on
being built as the same configuration that the running CMake was.

Steve W, can you post your tests as a patch or point us to a repo
where they are published so we can see how you're trying to test the
new CONFIG option?

Thanks,
