Status: RESOLVED INVALID

(Core :: Layout: Text and Fonts, defect)

Description

[Manuel]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.5) Gecko/20031120 Firebird/0.7
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.5) Gecko/20031120 Firebird/0.7

Example and Screenshots: http://stud.fh-heilbronn.de/~mcarrara/firebird

The minutes are not lined up at the top of the inline element. Several
screenshots from mozilla 1.5, konqueror and firebird are available.

The minutes should fully supertext. 


Reproducible: Always

Steps to Reproduce:
1. create an inline element
2. add vertical-align: super; and font-size: 80%;


Actual Results:  
Firebird renders the the inline element wrong (vertical-align: super)

Expected Results:  
Right behavior, see screenshots.

Like http://bugzilla.mozilla.org/show_bug.cgi?id=112502 but this time on Linux

Is this still a problem with the latest nightlies?  The GRE is the same.

This testcase behaves exactly the same in Firefox and SeaMonkey. If it's a bug,
it's a layout bug and not a Firefox bug.

All superscripts go to the superscript baseline of the parent's font.  This
can't possibly align the tops evenly for all possible font sizes of superscript.
