RadzenDataGrid and AuthorizationHandler

Hi everyone,
I found a problem with radzen datagrid when inside an AuthorizeView with Policy argument.
I'm implementing a Policy-based authorization and I created a requiremenHandler class and its requirement class. All the authorization system works as expected but when I insert a radzen datagrid with virtualization and loaddata the page continuosly reload.
It only happens if I use usermanager.getuserasync inside the requirementhandler class.

I hope i'm get explained.

I have created a new project from scratch and still happens.

Somebody has been experimented something similiar?
Am I missing something?

Thanks in advance:

Virtualization requires height to be specified.

Sorry by the delay. Height was specified.

I meant that height already was specified (not that I specified height and works), but still not working. Any news on this?

I'm afraid that I don't know what might cause such problem.
