Feature request
Currently the slider supports an onChange and onRelease event - it would be useful to also have an onGrab (or similar) event which is invoked when the user grabs the slider handle without releasing it.
Examples
A scenario when this would be useful is when using the slider as a scrubber control for a video. If the value of the slider is updated due to the user grabbing the handle and sliding, we would want to:
- Immediately reflect the new value in the slider so that it stays responsive; but
- Debounce the updates that tell the video to load at the current time. Otherwise we end up loading/trying to show a lot of "intermediate" frames that just get dropped as the user slides the handle.
