HTML tags content editable?

[ahamelers]

If HTML tags are included in markdown, and that markdown is loaded to the editor, it seems the entire line (including anything inside/after the tags) is put in a span like:

<span data-value="<div> some text" data-type="html" contenteditable="false" class="">&lt;div&gt; some text</span>

Users then cannot edit the HTML tags, or any text in the line, and if the user clicks backspace it deletes the whole line.

I have tried to change this, or at least make this contenteditable="true", by replacing and by extending the preset-commonmark htmlSchema, but I've been unsuccessful so far. Can anyone recommend what I should actually do? I would like to make the whole thing regularly editable, but barring that, limit the uneditable portion to the actual tags.
