Travel moves seam to have less resolution than the rest of the print, making them cross perimeters.

Describe the bug
On internal curves, with avoid crossing perimeters on, the travel moves still cross perimeters. It looks like the travel moves are calculated at a less resolution than the rest of the print moves. this causes imperfections because it makes it travel into perimeter possible even more than without "avoid crossing perimeters", because on internal curves, it crosses perimeters multiple times.

To Reproduce
Steps to reproduce the behavior:

1. Enable Avoid Crossing Perimeters,
2. Import a model that contains an internal curve (not a circle), read as a half moon shape for example, or just use the STL I provided.
3. Check the internal curves travels, at the right angle, you can see the perimeters being crossed by the travel moves.

Note: Changing the viewing angle hides or shows the issue a lot, keep the camera angle as low as possible, see screenshots.

Expected behavior
It's expected that the travel moves follow the perimeter line exactly, and not at a lower resolution, causing it to take shortcuts and cross perimeters

Screenshots



Note about the angle, if you look from the top, it's barely visible:

however if you look from a lower angle, you see it very well:

Desktop (please complete the following information):

• OS: Windowa
• tried in Version 2.3.56.7 and 2.3.57.3

Changing the angle of the object in the plate does change the issue a bit, some angles are better than others, but I couldn't get a perfect slice.

Update: After sharing this on discord, I was given a config.ini to test it out and it does not happen on the provided config, but it does on mine. So it probably depends on some setting.
