* Observes newly added section elements and sets an 'input' event listener on .applies-to inside.
* Observes newly added section elements, and sets these event listeners:
* 1. 'changes' on CodeMirror inside
* 2. 'input' on .applies-to inside
* The goal is to avoid listening to 'input' on the entire #sections tree,
* which would trigger updatePreview() twice on any keystroke -
* both for the synthetic event from CodeMirror and the original event.
