Description

I noticed that a user can not scroll to the exact position of the button on the underlying bar, this causes the button to snap abruptly to the final position when the user releases the touch event.

Research direction
Investigate the touch event handling and scrolling logic in SpaceTabLayout to understand why the button does not snap smoothly. Check the comments in the issue for any insights or attempted solutions. Review the custom view's onTouchEvent and scrollTo methods to identify where abrupt snapping occurs and how to interpolate the final position.
