Dupe of Bug 120154? (see bug 204002 comment 3)

Bug 204002 is a FF bug duped against the general Browser bug 120154. Why? I guess because this rendering is done in the shared code (almost only the GUI is different). So IMO this is not FF specific. Mozilla and FF have the same behavior on this.

I have duped to Bug 204002 as it does contain more information, even tho it has since been duped. Reporter, If you feel this is incorrect, please, feel free to reopen this bug. -Robin *** This bug has been marked as a duplicate of 204002 ***
