A space in a lang attribute makes Firefox use a wrong font size in lines that do not contain accented characters, e.g.
  <textarea name="details" rows="5" cols="10" lang="fr "></textarea>

Reproducible: Always

Steps to Reproduce:
1. Open the HTML file that will be attached.
2. Enter
     line 1 e
     line 2 é
     line 3
   in both textareas.
Actual Results:  
The first textarea is incorrect: wrong size of the box, lines without accented characters also have a wrong size.

Expected Results:  
The first textarea should be like the second one.

Maybe related to bug 390064 somehow?

I don't think so: I can't reproduce this bug.

In fact, the problem is related to the fact that for the Monospace font, I have Monaco in "Western" and Courier in "Other Languages". If I get it to Monaco too, the problem disappears. So, it seems that there are two bugs:
1. "fr " is seen as "other language".
2. The font size depends on the language declared in the source (instead of what the user writes in the textarea).

I can't reproduce this bug either.

Setting OS to All since I can reproduce the bug under Linux/ppc after changing the monospace font of "Other Languages".
