Bug Description
The only way the WWW author has to know the what size of type is well readable by a user is the default size selected by the user. When a font is displayed at a size smaller than the user's default font size, that creates a usability and accessibility problem. This is more widespread a problem than only affecting those who's eyesight is so poor that they count as disabled.
Some things which make it difficult to ensure that all content sufficiently sized are things such as:
.extra-
font-size:smaller
It is possible, if sufficient care is taken, to apply these rules so that none of the content gets shrunk so that it is smaller than the size of the user's default font. If these are applied to the user's default text size, the result will be a font which is too small. Easier is to not specify any size <100% or <1em or "smaller".

The class used in the this example should not be used. It is a vestige of the 2.0 style and that may mean that the base font of 1em; is not being used.
The font size must be one of the percentages supported by YUI and may but not ever be lower than 77% (10px if the user is using default os/browser sizes).
