Going to Music Explorer for the Now Playing song with multiple languages directs to the corresponding multi-language panel. I cannot recall the original behavior, but this seems correct to me as opposed to selecting only one language. (
It is, however, worth noting that one cannot go to a multi-language panel directly via the navigator afaik. The navigator only lists separate languages.)

Selecting a language in the navigator only shows albums containing at least one song in the given language
only. In the below image, the navigator indicates that one album contains a song in Mandarin, but no album is listed, because the actual song is in English and Mandarin. This has changed between the aforementioned versions.
