Medium Editor with displayed html code

Sorry if I propose a discussion again, but I have the problem of displaying the HTML code with Medium Editor, even after moving the css files (see Issue with Medium editor)
Where am I wrong?

Apply Inner HTML as in

Thanks Ben
but if I apply DynamicsEvent / Inner HTML what value should I give?

The issue is not related to the inner html settings.
There is something messed up with the files on your page. Please provide a link where we can check this.

I found the problem
on the page I entered a Server Site includes to include the menu
If I delete it, Medium Editor is correct
Now I have to look for the best position for inclusion

Unfortunately it seems that Server Site Include is incompatible with Medium Editor

There is no such thing as:

There is something messed on your page which breaks the editor functionality.

I check everything from the beginning

Hi Teodor
I created a test page and found the same problem
This is the link

There doesn’t seem to be anything messed up on this page

I found the solution
If I delete the bootstrap.min.css link in the menu file, the inclusion does not disturb Medium Editor
It is annoying not being able to easily manage the graphic of the menu but the problem is solved
