sorry for the delay...
This is intentional, but we know that there is a usability issue.
In CSS px, mm, pt etc. define absolute sizes [1].
So if we want to adhere to the CSS spec strictly I think we can't
just scale them.
On the other hand web designers just use px without thinking about
the implications. Also other browsers allow scaling of those fonts
afaik.
I think we have the following options:

* ignore CSS and apply font_factor also to absolute font sizes
* implement a zoom feature that displays everything larger (also
  images etc.
* check other browsers for more alternatives
