So even with the latest packages, I can still see issues when sliding the thumb on Skia for example

Branch to test + latest fixes for Slider Neumorphic Style (slider is commented for now on Gallery master branch): https://github.com/unoplatform/Uno.Gallery/tree/dev/agzi/NeumorphicSlider

Also, there is this issue even on Windows where sometimes the thumb does not go back to 0 completely (compared to 100) (We will need to investigate a bit more and open a separate issue as needed for this one normally)

The latest changes for the slider neuromorphic style are done in this PR https://github.com/unoplatform/Uno.Gallery/pull/961 But the Slider control is still commented as we still have the issue mentioned in the comment above that needs to be fixed
