REPL for aspnet core notifications is broken, it runs on first load and then fails to do anything if I change even a single character and then try to run it again

ASP.NET Core REPL - ASP.NET Core Components Playground & Testing - Telerik

Not sure that link will work but I'm talking about the notification that shows email message, error message and upload success

I'm seeing message in dev tools about  'isMobile is  not defined'

Running in Windows 10, latest version of Edge OR latest version of Chrome

Hello! When I try to populate a grid with data I can only get it to show the data if I don't use a nested object. For example:

An object like this I'd assume I could access by adding a grid column like this:

When I do it this way however nothing shows up although all items do load into the grid, they just don't show any text.

To make it show text I can only use the first level of properties in the object:

In this case I'd see the data in this property on the table.

Is this a bug or intended functionality?

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

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

For example:

Edit it REPL

Run, works fine

Make a simple change like changing height to 500px

Run, gives a blank screen on right side.
