Status: RESOLVED WORKSFORME

(Firefox :: General, defect)

This problem occurs when you look at Unicode HTML entities that map to super and subscripts in Mac/Firefox. Many of the entities are different sizes, and some are even invisibly small. This is not related to the HTML tags <sup> and <sub>.

Reproducible: Always

Steps to Reproduce:
1. Create a new HTML page (including a utf-8 charset meta tag)
2. Add various subscript and superscript entities (listed in the URL), such as &#8308;
Actual Results:  
All superscripts and subscripts should be equally sized.

Expected Results:  
Many of the entities are variably sized.

This page includes some additional information. Superscript 4 is particularly strange, as are many of the subscripts.

I can reproduce the problem in Firefox 2.0.0.11 on MacOSX 10.5.1 (Intel).
It works fine in a current Firefox trunk build.

Andrew, can you reproduce the problem in Firefox 3.0b2?

Please resolve this bug as WORKSFORME if it appears to work. Thanks!
