Reproducible: Always Steps to Reproduce: 1. open the example file Actual Results: Firefox crashes Expected Results: Correct rendering or maybe wrap the font-size to a fixed value...? I'm using Gentoo mozilla-firefox-bin package.
Save your work before opening... :)
Looks like it doesn't crash on Ubuntu's Firefox (checked with a friend of mine).

should we just change the cross platform 5000 to 2000?
?
... if you want to change size(PR_MIN(aSize, 5000)) to size(PR_MIN(aSize, 2000)) that would be fine with me. I don't like the current platform-specific limit
