Degradation of printing in vase mode after version 2.7.2

[IgorOhrimenko]

Description of the bug

The program makes a seam in the vase. I was printing a vase slice in the 2.7.3 and noticed that the printer prints slowly at the "seam", after printing the seam is visible and the seam is tactile. The same model slice in the 2.7.2 has no seam. In the preview of the slicer, the models look the same. I shot a video with real printed models: 2.7.2-vs-2.7.3.webm
