How to handle multisyllable/multiword ruby annotations in Japanese

[r12a]

My reading of the CSS Ruby spec is that if you set ruby-align to space-around (which is the default) and a single annotation for a single base contains two words in, say, Latin text (yes, i know it's probably very rare), then justification would be applied, causing one word to appear to the left, and the other to the right, with possibly a large gap between.

Here is an example i use for the same question to the clreq folks at w3c/clreq#125:

My suspicion is that actually one would expect the Latin text to remain centred, like this (imagine this was in Japanese):

Is this correct?

Both results can be achieved, so the interesting question is which one should be the default.

Now reaching out to JL-TF members on that, whether there is any strong condition(s) from their long experience.

Fwiw, the answer from the Chinese folks was that text should be centred and not justified. See w3c/clreq#125
