Not sure how to phrase it, but when I put these in a grid pane ugly things happen. Here is a modified version of your demo code that clearly shows the problem.

    The problem seems to be fixed (not sure what ugly things really means). Please put a more detailled problem description in next time, otherwise I have to guess what you mean.
