MKV output not copying over language subtags

Problem Description
I'm doing an MKV->MKV transcode with all audio tracks passed through. The source files use ISO 639-1 tags with ISO 3166-1 or UN M49 subtags to differentiate dialects such as Mexican, Latin American, and Castillian Spanish (es-mx, es-419, and es-es, respectively). Handbrake is dropping the subtag, so all three would be tagged "es". Attached are images from the MKVtoolnix GUI header editor showing a source file and Handbrake's output.
