#28 Union not joining adjacent rectangles

[Jon]

Thank you so much for this library. However, having a couple small problems with joining multiple adjacent rectangles. If I have union'ed two adjacent rectangles, and attempt to then union a third rectangle in, in certain scenarios, it produces two solutions when I believe it should only produce one (and only produces one in the C++ version).

I attached a picture of my particular scenario (blue is ptClip, green is ptSubject).
Code is below

        const sub = [{"X":-68,"Y":-75},{"X":137,"Y":-75},{"X":137,"Y":45},{"X":4,"Y":45},{"X":4,"Y":165},{"X":-140,"Y":165},{"X":-140,"Y":45},{"X":-68,"Y":45}];

        const clp = [{"X":82,"Y":45},{"X":226,"Y":45},{"X":226,"Y":165},{"X":82,"Y":165}];

        //get the union of the subject and clip polygons ...
        let initOption = 0;

        const clpr = new ClipperLib.Clipper(initOption);
        clpr.AddPath(sub, ClipperLib.PolyType.ptSubject, true);
        clpr.AddPath(clp, ClipperLib.PolyType.ptClip, true);
        const solution = new ClipperLib.Paths();
        clpr.Execute(ClipperLib.ClipType.ctUnion, solution, ClipperLib.PolyFillType.pftEvenOdd, ClipperLib.PolyFillType.pftEvenOdd);

Solution has two arrays, where the two paths are still completely separate. Am I setting up clipper incorrectly?
