with side comments not enabled, editor still injects "class="commentable-section" data-section-id="n" into markup

[deborah-ufw]

Hi! I saw this in a closed issue (237), but it is happening for me also.

Side comments are specifically disabled in my config.js...
// side comments disabled
comments: {
useSideComments: false,
allowAnonymous: false
},

but the editor is still injecting...
class="commentable-section" data-section-id="n"

into every paragraph when using the visual editor. If go in and remove the markup, save, and re-edit, it is all re-generated on every paragraph.

The editor also injects
<span style="font-size: 16px; line-height: 22.8571px;">
in bulleted lists and in a few other places. I'm not sure what triggered the span injection.

Thank you for this great plugin!!
