I was able to reproduce the error.

When I convert a project with no authentication type, it works. 

When I convert a project with Microsoft Identity Platform, I see the error. 

Hi

I have created a REPL here: https://blazorrepl.telerik.com/QHYGbTPk59IqOcEU51

to reproduce the issue I am talking about:

1. click on the cell
2. Press the 'Delete' Key
3. Press the 'Enter' Key

you will notice that the value displayed below the table is what was previously in the cell

I would have expected the value to be null which can be achieved via

1. click on the cell
2. Press the 'Delete' Key
3. Click outside the cell

Hi, 

I came across some unusual behaviour

I wanted to hide the default form submit button so I could put it elsewhere on the page but once I had an empty FormButton element on the page I was unable to print any more

<FormButtons></FormButtons>

a solution to my problem was to put an empty span in the element

<FormButtons><span></span></FormButtons>
