I want to use the HTML element <details> with <summary>.
Because this element is not included in the format select list I write it in code view.

Now, a strange incident occurs - you can see it in the video.
When I change to editor view (e.g. for editing) and go back to code view (e.g. for inserting another code block) the editor wraps the <details> block with a paragraph element AND also inserts empty paragraphs before and after.
What's more, just switching to the editor view will create the wrap and the empty paragraphs.
It doesn't happen with the TinyMCE editor
it doesn't happen when I put each <details> block in a <div> container.
I don't expect you to start looking for the error right away.
The workaround is easy especially using the great snippets feature.
Maybe someday you will have the time or desire to get to the bottom of the problem. (See your answer in /forum/108314-icons-for-using-html
