Commented Unassigned: Trying to convert svg content into pdf [1391]

I am trying to convert SVG content into pdf, svg content has one png base 64 content which is not being visible after converting to pdf.

Please help me sort it out this issue. The svg content is attached. I am using Magick.NET-x64 7.0.0.0.

Comments: Upgrade librsvg did not resolve the issue. I will investigate this some more and get back to you when I know more.
