Description

We had a property that was defined like this:

_progress: {
        isFloat: true,
        min: 0,
        max: 1
      }

The only code that set this property was this._progress = (scrollPosition - this.start) / this.duration;

However, we got e.g., negative values for _progress.

Is this something that is wrong with lively or did we use this feature wrong?
