Why is ChartsAxisHighlight Not Rendering in My MUI ResponsiveChartContainer?

I have a composed chart displaying specific data using two stacked area plots (with one hidden to represent an interquartile range) and an overlaid line plot for a time series.

Below is my component configuration:

JSXCopied
<ResponsiveChartContainer
               xAxis={[
                   {
                      //...
                       disableLine: true,
                       disableTicks: true,
                      //...
                   },
               ]}
               yAxis={[yAxis]} // similarly defined
               series={[
                   {
                       type: 'line',
                       id: `StateData-${energy}-25`,
                       yAxisId: yAxis.id,
                       // ...
                   },
                   {
                       type: 'line',
                       id: `StateData-${energy}-75`,
                       yAxisId: yAxis.id,
                       // ...
                   },
                   {
                       type: 'line',
                       id: `tract-${energy}`,
                       yAxisId: yAxis.id,
                       // ...
                   },
               ]}
               {// ...}
           >
               <AreaPlot />
               <LinePlot />
               <ChartsXAxis axisId="date" />
               <EnergyChartYAxis selectedChartType={selectedChartType} energy={energy} />
               <ChartsLegend
                   direction="row"
                   position={{ horizontal: 'middle', vertical: 'top' }}
               />
               <ChartsAxisHighlight axisHighlight="line" /> { // this doesn't do anything }
               <ChartsTooltip trigger="axis" />
               <ChartsGrid vertical />
               <ChartsGrid horizontal />
           </ResponsiveChartContainer>

The tooltip appears correctly, but the vertical dotted line that should be rendered by ChartsAxisHighlight is missing. I have tried various AI suggestions, reviewed the MUI code, and even attempted placing the ChartsAxisHighlight component directly in my chart without success.

What am I missing or misconfiguring to ensure the axis highlight displays as expected?
