docs: Schedules a job that will begin highlighting from <code>startLine</code>. The job runs for a short amount of time,
  after which it dispatches a {@link #event:HighlightEvent} indicating its progress, and yields. Follow-up jobs are
  scheduled automatically if there's more highlighting to be done.
