but potential to be one) and updated edit form dropzone handling so the
dropzone item card was not as distracting.

- Added new helper for simple dom element creation.
- Updated event naming to be "cm6" when codemirror-specific.
- Removed cm block border in md editor to prevent double bordering.
- Updated copy handling to fallback to execCommand.
- Fixed some keybindings not running as expected, due to some editor
defaults overriding or further actions taking place since the action
would not indicate it's been dealt with (by returning boolean).
- Fixed spacing/border-radius being used on codeblocks on non-intended
areas like the MD editor.
- Fixed lack of BG on default light theme, visible on full screen md
editor.

current editor (Likely non-cm related existing issue)

Updated selectable elements to be divs instead of buttons since Safari
akwardly does not focus on buttons on click.
Also standardised keyboard handling to our standard nav class.
Also addressed empty tag values showing in results.
For #4139
This changes how the editors interact with the parent page-editor
compontent, which handles auto-saving.
Instead of blasting the full editor content upon any change to that
parent compontent, the editors just alert of a change, without the
content. The parent compontent then requests the editor content from the
editor component when it needs that data for an autosave.
