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.
