Description

1. The entire Slider is focused instead of just the thumb.

The focus window should only follow the thumb while keeping the ability to tap anywhere on the slider to change value.
(this especially becomes problematic with RangeSlider)

Flutter	Android

2. RangeSider focus window is divided in half despite range thumb locations instead of just the range thumbs.

1. Focus window takes half the size regardless of the thumb location
2. If both range thumbs are located on one side of the slider, the focus window is still shown on the otherwise side, in an empty slider area.
3. Focus windows should be on the range thumbs
