Reads the currently dragged items from the DragDropService and triggers an
asynchronous evaluation if the dragged items are linkable.
While the evaluation requires asynchronous service calls, this method is
synchronous and made for cases where the environment is not made for
asynchronous behavior (e.g. dragover is always evaluated synchronous)
The synchronicity is based on multiple calls. Internally the first call triggers
an asynchronous call. Every following one for the same data is returning the state
of the call (PENDING or the result).
