Can you evaluate Arcade expressions in MapImageLayer popups?

Hi all -

I'm having trouble getting a popup for a MapImageLayer sublayer to evaluate an arcade expression I set in the expressionInfos property of the popup template. It works fine if I load the layer as a FeatureLayer, but it does not seem to work if I load it as a MapImage Layer. Does that popupTemplate feature simply not work for MapImageLayers?

My popupTemplate is below:

popupTemplate: {
 title: 'Other Tracts',
 content:
 '<ul><li>Tract Name: {TRACTNAME}</li>' +
 '<li class=\'{expression/check-othername}\'>Other Name: {OTHERNAME}</li>' +
 '<li>Conservation Priority: {TIER}</li>' +
 '<li>Site Name: {SITENAME}</li>' +
 '<li>Plan Name: {PLANNAME}</li>' +
 '<li>Plan URL: {PLANURL}</li>' +
 '<li>Comments: {COMMENTS}</li>',
 fieldInfos: [{
 fieldName: 'PROTDATE',
 format: {
 dateFormat: 'short-date'
 }
 }],
 expressionInfos: [{
 name: 'check-othername',
 expression: "if($feature.OTHERNAME == NULL){return 'invisible'}"
 }]
}

FYI - I reached out to Esri support and they confirmed that arcade expressions are not supported on MapImageLayer sublayers. More info here: Sublayer | API Reference | ArcGIS API for JavaScript 4.7
