Problem with thin wall in SuperSlicer 2.3.56

[graflash]

Describe the bug
The * .56 version does not create thin walls on the outer wall. All previous versions of SuperSlicer had no problems with this. I used the same settings in 2.3.55 and 2.3.56. I even saved the 3mf project to make sure everything was set up identically. Tried changing options for thin wall too, but no change. Temporary workaround is to change the width of the outer path.
It looks a bit as if thin walls are ignored when they cannot be made of two paths. Version .55 was able to create such elements from one path.
PrusaSlicer has the same problem.

To Reproduce
Use a model with thin elements extending beyond the object(sample stl in the attachment)

• OS: Windows
• Version: 2.3.55.5 and 2.3.56.7

In version 2.3.56.8 it now works correctly. Thank you very much.
