The slider and range slider should allow a drag handle tooltip to be configured as an input binding. This is useful for showing the current slider value, for example.

Something similar exists in jQuery: https://demos.telerik.com/kendo-ui/slider/events

It will be nice to have a dragStart and dragEnd (similar to JQuery UI Slider or Angular Material Slider) events for the Slider component which will provide a bit more flexibility upon user mouse/touch interactions. 

Would it be possible to add custom input attributes to the slider? https://www.telerik.com/kendo-angular-ui/components/inputs/slider https://www.telerik.com/kendo-angular-ui/components/inputs/radiobutton/custom-attributes#custom-input-attributes

For accessibility we want to add custom 'aria-labelledby' and 'name' attributes. When we add this to 'kendo-slider' component, nothing is read for it by NVDA.
