If you set an annotation with id is equals animations or label, the annotations is not drawn on the chart.

Config example:

annotations: {
  label: {
    type: 'point',
    xScaleID: 'x',
    yScaleID: 'y',
    xValue: 5,
    yValue: 5
  }
}

This seems to be related to the fallback because animations and label are 2 properties of annotations defaults and are objects.

EDIT: the annotations are not drawn because drawTime is undefined.
