Test suite fails with rsvg-convert version 2.54.3

[schuelermine]

I’m trying to fix the reanimate-svg package test suite in Nixpkgs, and we’re using a newer version of rsvg-convert, and this causes several test cases to fail unexpectedly. There’s also some unexpectedly passing cases in the Nixpkgs build but I think that’s unrelated. I checked a manual Cabal build on Ubuntu and NixOS with rsvg-convert 2.50.7 and 2.54.3, and 2.50.7 passes while 2.54.3 fails. I checked the output SVG between operating systems and they match.

Specifically, these tests fail (without further output):

• animate-elem-32-t
• shapes-ellipse-02-t
• shapes-intro-01-t
• styling-css-06-b
• text-intro-05-t

Here’s the golden image of animate-elem-32-t:

Do you believe these tests indicate a failure of reanimate-svg or are they fine to disable?
