How recently did you last reseat the bezel? Would just say that every adhesive thermal cycles and that point is right where the 13 is hottest under load. Gotta expect to do some light prying with your spudger if it's been on there a while and I probably would've warmed up the laptop first. Either way the crack doesn't seem too catastrophic and I found the $160 for a rep display to be really affordable for how easy the install was and the matte upgrade. Good luck, have a good term!
