// The Ruby `clipboard_button` helper sneaks a JSON hash with `text` and `gfm` keys into the `data-clipboard-text`
// attribute that ClipboardJS reads from.
// When ClipboardJS creates a new `textarea` (directly inside `body`, with a `readonly` attribute`), sets its value
// to the value of this data attribute, focusses on it, and finally programmatically issues the 'Copy' command,
// this code intercepts the copy command/event at the last minute to deconstruct this JSON hash and set the
// `text/plain` and `text/x-gfm` copy data types to the intended values.
