SmallPartsTray2 generates incorrect fingers for inner y dividers

[jkuzeja]

Describe the bug
SmallPartsTray2 generates incorrect fingers for inner y dividers. The fingers near the the front are correct, but the ones in the back are shifted by one finger width as far as I can tell. I discovered this when trying to put a box together. Not sure what version this is - it is whatever was public on Feb 10, 2024.

To Reproduce
http://www.festi.info/boxes.py/SmallPartsTray2?h=22&sx=164%2F4&sy=82&thickness=2.8&reference=0&inner_corners=corner&burn=0.08

short command line:
boxes SmallPartsTray2 --h=22 --sx=164/4 --sy=82 --thickness=2.8 --reference=0 --inner_corners=corner --burn=0.08

Expected behavior
When I went to insert the dividers, they had five fingers in the back section but there were only four slots in the back floor. (The sides were ok.) I flipped the back part of the bottom floor fingers in Inkscape to fix it. That reduced the number of fingers to four and put them in the correct place as well.

Screenshots or Drawings
The dividers as generated are like this (back fingers are to the left):

But I think they should look like this:

For reference, here is the floor back side:
