Bug Report

(potentially related to #791 and #866 or #970)

Steps to reproduce

Include a file as a .html and then as a code block, i.e.

[embed](embed.html ':include')

[source](embed.html ':include :type=code :fragment=demo')

raw files

rendered version

Tested in Chrome, Firefox and Edge

What is current behaviour

The code block overwrites the page content (after a short delay).

The order of embedding does not matter, and even if the linked files are different this will happen.

If either block is removed there is no issue, and it seems unrelated to the fragment nor highlight type.

What is the expected behaviour

Multiple embed blocks remain visible.
