Annotations can overflow out of the chart

Minimal example of this:

<div id="graph" />
<script src="https://cdn.plot.ly/plotly-3.1.2.min.js"></script>
<script>
var layout = {
  annotations: [{
    "text": "No data is available to display. No data is available to display. No data is available to display. No data is available to display. No data is available to display. ",
    "font": {"size": 20}
  }]
};

Plotly.newPlot('graph', {
  'config': {},
  'data': [],
  'layout': layout
})
</script>

Ideally this text would wrap so that it fits on the page

从使用 Plotly.newPlot 和 annotations 数组的最小示例开始，然后跟踪图表没有数据时注释文本的渲染方式。将生成的图表尺寸和文本布局与随附的屏幕截图进行对照。完成的标准是：较长的注释文本会换行，或以其他方式保持在图表/页面内而不溢出。
