/**
* Monitor a textarea and render a live preview of its content parsed as
* Markdown. The textarea needs to have the data attribute
* data-gts-preview-target set, and it should be an id of an element elsewhere
* in the document. The target element needs to contain at least a div element,
* which is where the preview will be rendered.
*
* When previewing, the target will be hidden when the textarea is empty, and
* shown with block display when there is content.
