    Default Unwanted TreeGrid Header resize on mouseover

    When I mouse over the header of some of my TreeGrids, the height of the header jumps to 30px, and stays there. If I collapse the view the TreeGrid is in, and then open it again, the TreeGrid header is set back to the correct height and subsequent mouseovers work fine.

    I set a break point in ColumnHeader$Head.activate():

    protected void activate() {
    if (!cm.isMenuDisabled(indexOf(this))) {
    XElement td = getElement().findParent("td", 3);
    int h = td.getHeight(true);
    getElement().setHeight(h, true);
    if (btn != null) {, true);

    and the value for h is coming back as 30 when it goes wrong and 21 when it works right.

    Oddly this happens on some of my TreeGrids, but not all, although I can not see any difference in the way I am creating them.

    I have been seeing this behavior since I moved to 3.0.0. I am currently using release 3.0.0-rc2.

    Thanks in advance.

    p.s. I also occasionally see some unwanted resizing of the widths of the right most column on the same TreeGrids that have the height problem.

    See below for before and after mousover.
