How to reproduce

1. Load attached project
2. Set Min. fan speed threshold to 50%, and layer time to 30sec
3. Set `Max fan speed threshold to 75%, and layer time to 8sec
4. Enable Keep fan always on
5. Enable Slow printing down for better layer cooling
6. Enable Force cooling for overhang and bridge
7. Set Cooling overhang threshold to any % between 10 and 50
8. Set Fan speed for overhang to 100%
9. Enable Spiral vase mode, or set Wall loops = 1, Top shell layers = 0, and Sparse infill density = 0%
10. Slice file
11. Change preview to show Fan speed

Actual results

When layer time falls between min and max thresholds, overhang fan speed is increased for overhangs according to chosen settings. When actual layer time is greater than fan_cooling_layer_time, the increased cooling for overhangs is ignored and remains at the 'min_fan_speed` set.

Expected results

Increased cooling for overhangs should be effective regardless of layer time or applicable print speed for the feature at that time.

Can confirm I'm seeing this exact same behavior, and it's ridiculously annoying.

The line type even says "overhang wall", but the overhand fan speed setting is completely ignored.
