CSS classes are ignored if they start with e then number

Summary:

So I have a magical SVG from my school.

When I preview it in my browser, it has a white font. When I open it in Inkscape v0.92, it has a white font.

However, when I try to open it in Inkscape v1.2, it has a black font.

Steps to reproduce:

• open Inkscape
• open the file
