 From the f2f minutes:[1]

>   http://wiki.csswg.org/spec/css2.1#issue-199
>   <fantasai> so line boxes should be created for inline-level content and
>              potentially marker boxes
>   <fantasai> collapsed-away whitespace does not create a line box
>   jdaggett: so you have a line box with no text in it. What font metrics
>             do you use for it?
>   dbaron: known problem
>   Bert: We need to pick a font for finding the 'ex' unit
>   jdaggett: We don't have a font-finding algorithm that works without text
>   several you want to check against the first available font
>   steve: match against the empty string. Every font will match

Bert's already addressed this issue, right? [2,3]

>   <TabAtkins> http://lists.w3.org/Archives/Public/www-style/2010May/0698.html
>   discussion of the phantom line boxes in 9.4.2
>   http://lists.w3.org/Archives/Public/www-style/2010May/0698.html
>   ...
>   fantasai: You need the phantom line boxes to handle abspos static positioning
>   fantasai: but you need to ignore it for margin collapsing
>   <ChrisL> calling it 'potential' line box (which later resolves to no
>            line box, or a real line box, may be better than 'phantom'
>   ACTION: Tab propose text for CSS2.1 Issue 199
>   <trackbot> Created ACTION-255
>   <Arron> I feel that potential is a better term than phantom

This issue is intimately related to the first three issues in [4].
