Thin wall generation inconsistent across Z-levels - wedge example #2800

I've been having issues with thin wall generation and I've boiled it down to a relatively simple example - a wedge. The model should generate consistent gcode across all Z-levels but the thin walls at the tip of the wedge are seemingly random. With thin walls disabled, the model slices exactly how I expect - down to a minimum of 2 perimeter lines then ignoring the thin part of the tip.

Picture with 1000 words (Slic3r 1.1.7):

Slic3r settings:

Generated gcode:

Version 1.2.6 produces notably different but still "random" results:

Thank you for the report! This is now fixed, and I think this commit also fixes some other issues that were reported here in GitHub.

Thank you very much. While this did fix one of the major issues I had, it also created a few more (or at least somewhere between 1.2.6 and now created a few more issues). More reports to follow :)
