The PointNumber property in EventDataPoint is returned as an array when a heat map cell is clicked on. This causes an json parsing error on the client side and the C# click event never actually activates.
I was able to fix this issue relatively easily by adding the Plotly.Blazor source code to my project and changing PointIndex from an int to an object.
