(Core :: SVG, defect)

Description

[Paul A. Bristow]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-GB; rv:1.8.1.8) Gecko/20071008 Firefox/2.0.0.8

baseline-shift, supershift do not display in SVG graphic files.

So graphs cannot be labelled correction with X-axis like area (m^2)

SVG baseline-shift = "super" has NO effect.

This is a major problem for my application and many others trying to show sub and superscript :-((

There are some reports of this before some time ago, but no fixes.

 (and IE is fine).



Reproducible: Always

Steps to Reproduce:
Create an svg file just the following:

<?xml version='1.0' standalone='no'?>
<!DOCTYPE svg PUBLIC '-//W3C//DTD SVG 1.1//EN' 'http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd'> 

<svg version='1.1' xmlns='http://www.w3.org/2000/svg'>
    
    <g fill ='red'>
        <text x ='10' y ='25' font-size ='130%'>
            <tspan>
                e = mc 
                <tspan baseline-shift ='super' dx='-4' dy='1' style='font-size:60%;'>
                    2
                </tspan>
            </tspan>
           </text>
    </g>
</svg>

It should display the famous equation with a superscript 2 of course.

But the 2 is on the line instead of above it.

Actual Results:  
e = mc2

Expected Results:  
e = mc ^2

Made the 2 a superscript.
