I do not understand this…can you explain a bit more?

All pages with ruby and without lang will break.

So, not 1 please.

I think the question is how to justify Bopomofo, rather than the default value of ruby-align.

This real-world page[2] indicates that Bopomofo is a space-delimited scripts, so I'm guessing we do not want justify between Bopomofo, similar to Korean, where Hanja justifies between letters while Hangul does not.

I would love to see if there were any real example of justified Bopomofo, but IIUC Richard has been trying that without success, even for single example.
