onDragCompleted return unexpected lowerValue?

Hi, here is the issue I am facing. When I tap once and release on the same location, the lowerValue return from onDragStarted & onDragCompleted is different.

Kindly refer screenshot to visualise the scenario: https://photos.app.goo.gl/M9kcay5PEWZnTsqF9

For example, I tapped the area in between 100Mbps and 500Mbps and released. onDragStarted lowerValue: 33.3336 onDragCompleted lowerValue: 0.0

As the result, the handler moved to 50Mbps when rebuilt.

Appreciate if anyone can help to verify is this a bug or is expected behaviour of xlider. Would provide any info if required. Thanks.

Hi. Could you provide a sample code so that I can reproduce the error?
