Wilcard pins added via drag and drop retain the type of the source even after breaking the link. This will not reproduce if the output wildcard pin is created through the details panel.
See screenshots for examples
Result: The Output Wildcard pin changed to the type of the Self reference
Expected: The Output pin should remain a Wildcard pin
