But did any browser ever support it?
Yes, I just re-checked. Among my current browsers, the ones that don't use Apple Webkit all handle it--or try to--with varying success. Boldface is a problem, since it tends to run small in computer fonts and then they get confused.
So that's Opera yes, the Mozillas (Firefox and Camino) yes; Safari, Chrome and the text editor's www preview no. (Yes, I realize that sounds backward!) I did not try Lynx ;)
If you are curious, try this:
The Notes and Vocabulary (i.e. 80% of the book, because it's a textbook) are mixed serif and sans, so that's where font-size-adjust would really be useful. Most of the time I'll just set sans-serif to a smaller size, but this time I tried the alternative version.
