I tried it out and the handle was still stuck at the top. Maybe I did something wrong, but it seems to me that a better way would be to change the fallback in ensureHandleVisibility to not be 0 but something like 200:

I like Tim's idea of using a relative value for the default but maybe it will be harder to implement the handle dragging since you'd have to convert pixels to relative values there as well.

I noticed that if I use position relative, I will have to make numerous changes however I decided to leave the button as is because it was always getting overridden by the fallback function. You and @tim-schilling can test it out now to see if it works now.
