The slowness is happening only if we tap or change the value using setValue, drag looks fine.
If you look into init function there is listener for change event.
I'm using reference to thumb inside that, although its changed the thumb position refers to previous one. That's why i'm using a delay of 200, which creates the slowness.
Try this inside defer and outside and tap the single slider component, you will see the difference.
i'm expecting thumb object to have the "x" value after the change.
