From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.0rc3) Gecko/20020523 BuildID: 2002052306 Issue three of this bug tracking page shows a problem where id class ID1 is assumed the same as class id1. The recommendation says case sensitivity is on! msie and opera also get this wrong. one of the few places Amaya gets things right ;-] ;-] At one time you had this working but i suspect someone wrote a make_all_upper function for something and it is being used where it should not be !!! Reproducible: Always Steps to Reproduce: 1. View the test page 2. note that both lines are same effect 3. read style to see effects that should occur. Actual Results: wrong style rule applied because of bad assumption Expected Results: each line should have own style rule applied
Your suspicion is correct. It was decided that too many people just got this wrong on real web pages, and it would need to be supported in non-strict mode. See bug 93371 and http://mozilla.org/docs/web-developer/quirks/ . If you add a doctype such as "<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0//EN">" then this will be handled per spec.

Verified that testing strict specification compliance in a page that is in quirks mode is pointless.
