What is the reason for this additional bit of code? If dispatcher is null, then it probably should throw. You are asking it to run on the specified dispatcher, and it may give random results if there is no dispatcher.

@mattleibow When the dispatcher is null, the method currently executes the action directly, which may not align with expectations in certain scenarios—such as in the PropertyChangeBindingsOccurThroughMainThread test, where InvokeOnMainThread is expected to be called when isOnBackgroundThread is true.
To address this, the additional logic uses Dispatcher.GetForCurrentThread() as a fallback to ensure the action is dispatched appropriately. This approach helps maintain thread-safety and ensures consistent behavior even when an explicit dispatcher reference is not available. It also allows mock dispatchers in test environments to be respected, avoiding unintended test failures or bypassed execution paths.
This change preserves expected behavior without altering the existing public contract and provides a safer fallback in cases where the dispatcher is not explicitly passed. Please let me know if you have any suggestions.

I think is fine is just an extra check, it will not throw and fallback to the previous way of just calling the action() if IsDispatchRequired on the new found dispatcher is false.
