This is what I had in mind:

"
The line box height is the distance between the uppermost box top and 
the lowermost box bottom.
"

But, anyway, if "sideways"-ed latin text inside a line box whose 
dominant baseline is central is not going (and is not supposed) to be 
offset horizontally, then its impact on line box height is inexistent.

In c) of

http://www.gtalbot.org/BrowserBugsSection/CSS3WritingModes/text-orientation-mixed-vs-sideways-004.xht

if the "W" and "S" glyphs (text-orientation: sideways) are supposed to 
be perfectly aligned with the "M" and "X" glyphs (text-orientation: 
mixed), then the line box height should not grow, should not increase.

My reasoning is: if the "W" and "S" glyphs (text-orientation: sideways) 
are supposed to be offset by 30%, offset leftwardedly (toward the left, 
toward the descender side) in comparison to the "M" and "X" glyphs 
(text-orientation: mixed), then I think the line box height should be 
adjusted accordingly, should increase by 30% too.
