JSException in SfComboBox and SfDropdownList

When I put a ComboBox or DropdownList in a SfDialog, after the dialog is closed an exception is thrown.

If the ComboBox/DropdownList is opened (expanded) before closing the dialog, then the exception is not thrown.

This exception is not easy to observe since it's thrown in some kind of fire and forget Task, one easy way to observe it is to attach an event to TaskScheduler.UnobservedTaskException and wait for GC to finalize the orphaned Task, since that Task returned an exception and have not been awaited, the TaskScheduler will throw an UnobservedTaskException.

The app is Blazor Hybrid, not sure if the issue exists even on Blazor Server and Blazor WebAssembly, also I'm on Win11 (missing from the OS options) .NET 10.

Attached to the message there is the full exception tree printed out.
