UI Extension Chart Tooltip Issue

I use the LineChart component like this

<LineChart data={usageRecordsData}
 axes={{
 x: { field: 'Start Date', fieldType: 'datetime' },
 y: { field: 'Sum', fieldType: 'linear' },
 options: { groupFieldByColor: 'Breakdown' }
 }}
 options={{
 showLegend: true,
 showDataLabels: true,
 showTooltips: true,
 }}
/>

However, the tooltip of each datapoint only displays the datetime rather than the value:

Changing the `fieldType` to `category` actually leads to the desired result of displaying the y-axis values on the datapoints, but the x-axis labeling is not appealing:

Am I missing something here or is this a bug?

Hi, @TobeH :waving_hand: Thanks for your question. Including your code snippet and screenshots is always appreciated. I see that @aanchalshethHS answered a similar question last week. Hey @zach_threadint @SteveHTM do you have any experience here?

Thank you for taking a look! — Jaycee
