[HxGrid] Issue with disposed EF context when page reload

[introw]

Hi,
HxGrid throws this exception when page is reloaded.

System.AggregateException: One or more errors occurred. (Cannot access a disposed context instance. A common cause of this error is disposing a context instance that was resolved from dependency injection and then later trying to use the same context instance elsewhere in your application. This may occur if you are calling 'Dispose' on the context instance, or wrapping it in a using statement. If you are using dependency injection, you should let the dependency injection container take care of disposing context instances. Object name: 'ApplicationDbContext'.) ---> System.ObjectDisposedException: Cannot access a disposed context instance.

Thank you for investigation.

This error is not specific to our components and relates to a dependency injection lifecycle + Blazor server lifecycle.
