Subject: feat: swith focus map by tab key and click

* Use data-focus attribute and MutationObserver to move map-container
  between Sementic HTML and Showcase.

* Currently set return value of docuement.onkeydown in editor, then
  reset onkeydown function in dumbymap. Maybe there is a better way?

* CSS to make placeholder not so obvious
