Leak in headliner near sunvisor

[Redfish5050]

So I have no sunroof. My headliner is coming undone right where it meets the windshield. When it rains heavy I noticed a drip from both the drivers side and passenger side right in front of the visors where where it meets the windshield. I peeked under it best I could and everything seemed fine. I found some threads about leaks from the shark fin but they were all around the 2016-ish models. Is there a common problem with this or is m Yukon just weird?

Consider the body seam weld above the sun visor:
