I included a nuget package, but the code will not compile because it can't find the package symbols.

For example:

https://blazorrepl.telerik.com/cbPPOzcQ05pZuq4a09

From this page: Hierarchy in ASP.NET Core Grid Component Demo | Telerik UI for ASP.NET Core

Edit it REPL

Run, works fine

Make a simple change like changing height to 500px

Run, gives a blank screen on right side.

The Basic Usage Demo of the DataSource does not run in REPL.

1. Run the demo https://demos.telerik.com/aspnet-core/datasource
2. Only the headers are displayed
