/**
 * `<vevent-description />`

A text representation of a VEvent. Used as the summary tab of our
popup windows, and in the sidebar.

When redrawn, it looks for an HTML-tag inside its template having the
attribute `data-property` matching the properties name. If one is
found, it looks in the `formatters` table
({@link formatters}), for a field matching the property value, and
defaults to the key `default`.
