How to preserve inline HTML when converting .md to .adoc?

How to preserve inline HTML when converting .md to .adoc?

When I convert my Markdown to Asciidoctor, an inline image gets removed:

Input:

---
> title: Cats
> --- 

**Subpages: [Tigers](/cats/tigers/)**
>
> <img style="margin:5px; float: left;" 
> src="https://placekitten.com/96/139"/>Cats are animals.


Pandoc command:

pandoc --verbose -s -f markdown+yaml_metadata_block -t asciidoctor page.md

Output:

= Cats
>
> *Subpages: link:/cats/tigers/[Tigers]*
>
> Cats are animals.
>

How do I get the image (and other inline HTML such as `<sup>`, 
`<aside>...`) preserved in some form? Is there some flag/filter/extension I 
can pass to Pandoc to keep those? 
If Pandoc at least printed the file name and line, fixing those manually 
would be easier...

Thank you for any tips!

Cheers, Jakub

These  bits are raw HTML, and currently the asciidoc writer
omits any raw blocks and inlines except those marked "asciidoc".

That's because asciidoc(tor) doesn't have a dedicated syntax
for raw HTML.  There's a "passthrough" syntax, but this just
passes things through regardless of the output format; it
wouldn't be appropriate to pass through raw HTML to non-HTML
formats, so we didn't use this.

You can use a filter to convert raw inline HTML  to this
passthrough format.  Untested: run with
pandoc --lua-filter passthrough.lua my.md -o my.adoc

-- passthrough.lua
function RawInline(el)
  return pandoc.RawInline('asciidoc', '+++' .. el.text .. '+++')
end
