Actually the cabinets split from both directions, especially from torsion around leg bolts.
Install added plates and top corner brackets, or be willing to accept the consequences. It is part of our preventative bulletproofing games before placing titles out for operation. The issue has been present with Stern games since around 2016, but I don't track every release and compare every cabinet since we add protection anyway. The whole decal overlapping simply make damage easier to spot. I discussed in detail in an earlier post several years ago, and why BLY/WMS added these brackets in the first place in 1993 along with better mitered joints.
Glues such as Titebond will not provide the added protective shear strength after damage has started at the joint. It simply fills the crack or miter void.
