FWIW I tried Amayama for the runroof glass (63201-60023) at least a year ago and at first it seemed like it would happen but later the order was canceled as they didn't want to ship the glass.
That is the cable cover, known for water to leak past the screw threads but also
IIRC that area is a low spot which allow water from the drain pan to overflow.
I used something like butyl rubber (3M Window Weld) to build a small dam in the low area and put some under the cable cover, IIRC it...
