Sliders in exposure module are not correctly reset after using pipette
I noticed that the sliders (specifically the sliders knobs) are not correctly reset after using the pipette tool to let darktable guess the values for black level and exposure.Steps to reproduce the bug:
- Open image in darkroom
- Activate exposure module
- Use the pipette tool (see Image 1)
- Reset using the module reset button, the knobs are now not in the middle, but the value of the sliders are zero as expected (see image 2)
You can also modify the slider now, but the zero/origin remains at the false position (see image 3).
