When slider capture mouse, no more events propagated to parent, how to propagate them anyway?

[hellozyemlya]

I implemented functionality, where moving mouse over component makes controls (seek bar and volume slider) visible, and for period of inactivity makes them invisible again. But when I grab slider, it disables event propagation to\from parent, making timeout happen, and my controls hidden.

Is there a way to propagate mouse events back to parent with Slider?
