Unobserved Task MudExBaseFormComponent

[mateuszgutowski]

Unobserved Task Exception: A Task's exception(s) were not observed either by Waiting on the Task or accessing its Exception property. As a result, the unobserved exception was rethrown by the finalizer thread. (An attempt was made to transition a task to a final state when it had already completed.)
