What causes "Error: Microsoft.JSInterop.JSException: Could not find 'plotlyInterop.newPlot' ('plotlyInterop' was undefined)."?

I use Plotly Blazor with Server-side Blazor. When I open new window containing Plotly graph using JS Interop:

JSRuntime.InvokeVoidAsync("open", System.Threading.CancellationToken.None, $"/chart/{b}/{(int)readingType}", "_blank");

I get an error:

Error: Microsoft.JSInterop.JSException: Could not find 'plotlyInterop.newPlot' ('plotlyInterop' was undefined).Error: Could not find 'plotlyInterop.newPlot' ('plotlyInterop' was undefined).

From what I understand the javascript is missing in this page. I followed the lead of violating Content Security Policy but this took me nowhere. When I reload, clicking Refresh button, the page reloads and works normally. The script was loaded.

The issue only occurs in development environment while using IISExpress as a server with Visual Studio 2022 Version 17.3.6. When I deploy on Nginx running on Raspberry Pi, I do not get this error.

Any suggestions how to resolve the issue would be appreciated.
