Vue-echarts: tooltip working on all but one of my charts. Why?

Question

I have several echarts in an application I develop. I'm using V4 of echarts (can't upgrade just yet) and following the documentation for tooltip usage as found here: https://echarts.apache.org/v4/en/option.html#tooltip All but my latest one are showing the tooltip just fine. I cannot see any difference between my new one and my old ones.

I have explicitly imported the proper modules as outlined in the answer to this question: Apache ECharts with Vue does not show Tooltip just like I did for my old ones.

I use vue files with the template on top, script in the middle, and css at the bottom. The chart is defined in the template thus:

<echarts
  id="alertPie"
  :options="option"
  class="alertChart"
  autoresize
/>

In my scripts section, I have these imports:

import 'echarts/lib/chart/pie'
import 'echarts/lib/component/tooltip'
import 'echarts/lib/component/title'
import 'echarts/lib/component/legend'

The "option" for the chart is a computed field defined thus:

computed: {
    option () {
      return {
        backgroundColor: '#efefef',
        textStyle: {
          fontStyle: 'italic',
          fontWeight: 'bold'
        },
        title: {
          text: 'Alert Adoption',
          subtext: 'Count by Alert',
          left: 'center',
          top: 10,
          textStyle: {
            color: '#ee0022',
            textBorderColor: '#000000',
            textBorderWidth: 2,
            textShadowColor: 'rgba(0,0,0,0.5)',
            textShadowBlur: 4,
            fontWeight: 'bold',
            textShadowOffsetX: 2,
            textShadowOffsetY: 2,
            fontSize: 28
          },
          subtextStyle: {
            color: 'black'
          }
        },
        tooltip: {
          trigger: 'item',
          formatter: '{a} <br/>{b} : {c} ({d}%)'
        },
        legend: {
          // orient: 'vertical',
          // top: 'middle',
          bottom: 10,
          left: 'center'
        },
        series: [
          {
            name: 'pie',
            type: 'pie',
            data: this.alertPieData,
            radius: '40%',
            center: ['50%', '40%'],
            selectedMode: 'single',
            itemStyle: {
              emphasis: {
                shadowBlur: 10,
                shadowOffsetX: 0,
                shadowColor: 'rgba(0, 0, 0, 0.5)'
              }
            }
          }
        ],
        animationDuration: 2000
      }
    }
  }

The pie shows the data correctly. The title and legend both show correctly. Of the imported items, only the tooltip is not working.

Like I said, my other charts are built the same and tooltips work. What could I have missed? I've stared at this and compared to my working examples and don't see any differences (other than data sources and title/label changes).

Any ideas?

Data sample below:

[ { "name": "Acthar Gel Med Order Alert", "value": 10 }, 
{ "name": "Anticoagulation / Hemoglobin Alert", "value": 6 }, 
{ "name": "Anticoagulation or Dual Antiplatelet / Hemoglobin Alert", "value": 7 }, 
{ "name": "Berinert Alert", "value": 10 }, 
{ "name": "Blood Culture Identification Alert", "value": 13 }, 
{ "name": "Clostridium Difficile Alert", "value": 9 }, 
{ "name": "Clostridium Difficile Lab Order Alert", "value": 15 }, 
{ "name": "Controlled Substance - Pyxis Removal / Late Admin Alert", "value": 13 } ]
