=============Resolution==================
It is normal for water to bypass the silicon seals around the sun roof. This is by design.
There is a trough system that captures the water, and drains it to all four corners of the vehicle.
The water was NOT making it to the trough system. Instead, some of it was being dumped into the track, used for the sliding sunroof.
There is a "tray" that moves with the sliding glass. This tray is an important part of the trough system.
One side of this mobile tray, had come loose from its "hinge".
So water coming off the glass, misses the tray, trough, and instead lands in the track.
The track then dumps the water directly into the cabin area for the vehicle.
This is not a hard job by any means, and doesn't take a lot of time.
The most exotic tool, is a large Torx bit for the seat belt buckles. Otherwise all normal tools.
You may require a helper when taking down and reinstalling the sunroof frame assembly. (avoid bending/distorting it)
Fold down the rear seats and lean the front back as far as possible.
If you don't fix this, mold can develop. You will see water pooling in the spare tire well, as well as staining at the rear of the headliner.
It is a good idea to replace the light silicon grease lubricant, that has been washed from the track.
Also a good time to use that light silicon grease to lube up the cable system for the roof. (warning: petrolium grease may break down the plastics)

The tray just snaps back into place. I may make a slight modification, to help prevent a repeat; not that I understand what caused it since the module/motor can't be easily operated outside the vehicle.
Took it into the dealer. Had one week. Resealed windshield. Replaced sun roof due to unusual noise on tilt. Got it back with some rattles. Different, but sunroof still made an unusual noise on tilt. Inside of windows still fog-up when parked in the sun after rain. Nothing done about clack noise on clutch release. They were nice enough to detail the exterior, but paint was full of swirls and the rear ST emblem knocked loose.
Took it into the dealer. Had two weeks. Smelled like they did a crap-ton of caulking. Got it back with missing paint, unfinished roof rails that were peeling up, a warped rear panel that wouldn't stay in place, additional rattles, a MASSIVE gap between the body and rear hatch. Inside of windows still fog-up when parked in the sun after rain. They also had instructions to determine the cause of a clack noise on clutch release and contact me with diagnosis prior to doing any work. They failed to contact me, unnecessarily replaced the axle shafts, (which made no difference,) and didn't do any post-work testing or alignment. Lock-to-lock turning is now different. Replacement axle shafts are just as rusty/ugly as the original.
So needless to say, I'm taking my own advise and warranty or no warranty, are back to doing my own work. This combined with the ultra-thin minimum possible thickness paint, Ford is unlikely to get my next purchase. There's simply too much competition to put out products and "service" like this.

Update re Lubricants, Weather Strip and Fasteners:
Here are high resolution photos (click on link) of the headliner staining and sunroof...Update re Headliner Stain Removal:

Update re modifying Sunroof to prevent this problem:
