Slider : handleHovered = true but not hovered will not update slider data

Double click message will not into the
1. -> onExited : handleHovered = false
2. -> onPressed will into if (handleHovered) {...} even we release the handle
hovered.
3. -> Then will cause not updateHandlePosition( ) so, this process will not
post this message to Slider :: onSliderValueChanged() {..}
4. -> So click will not change the UI
