Remote url failed to load in asciidoctor-epub3

Question

I'm unable to generate/view the image from a remote URL while generating the Mobi. Whereas it works for asciidoctor when converting adoc to HTML

Code look something like this

You can find image:https://upload.wikimedia.org/wikipedia/commons/3/35/Tux.svg[Linux,25,35] everywhere these days.
