When a TelerikSlider is placed inside a layout that contains a view above the slider (e.g. a BoxView) that toggles visibility based on the slider’s value, an unexpected behavior occurs:

If the user is clicking on a slider value that toggles the visibility of the green box to change (either show or hide), the slider thumb continues to follow the mouse cursor even after the drag should have ended. This continues until the user explicitly clicks somewhere on the slider again.
