Mousing off the end of a slider drag doesn't change value about slint

[tronical]

This patch fixes it for me (the Qt slider already implements this):

but I'm having trouble making at test for it.

I tried this, but somehow the pointer event isn't triggered:

@ogoffart @FloVanGH do you have any idea what I'm doing wrong?
