Cura 4.6.1 z-seam with coasting is not on the sharpest corner

[Daelril 0]

Hi everybody. I don't understand why, but Cura puts the z-seam on a round part of the object while there is a 90° angle on the right side, if i choose Sharpest Corner. In fact i can chose to put the z-seam there with User Specified, but this behaviour by Cura is really weird. I could remove Coasting, but right now it is the only way i have to compensate for some imperfections on the walls that i still have to figure out.

Sharpest corner really doesn't work reliably for a lot of models. As you have found, user specified works better.
