Prusaslicer 2.7.4 doesn't always recognize floating parts #12670

Description of the bug

So, I was printing a car model (the file only contain part of the car because it is a paid model, but it is enough to recreate the issue) and the corner of the wheel well was floating, due to the angle I was printing at. Well the slicer did not recognize that the corner was floating and it didn't mark it in dark blue and thus, because I was using custom supports and only applying them in the dark blue areas, I didn't think to double check because I didn't think this would be an issue

Overhang Fail.zip

0.2mm layer height, 0.4 nozzle. This should be enough to make the bug occur

Just providing a slightly better view of the issue since your original picture confused me more than anything image
