Hello,

"
In vertical writing mode, the central baseline is used as the dominant 
baseline when text-orientation is mixed or upright.

I do not understand how and why there can be a central baseline for text 
with 'text-orientation' set to 'upright'. How can this be?

of vertical text in 2 line boxes has text-orientation set to upright.

Now, how can the baseline-alignment of glyphs be using the central 
baseline here?
