Summary:
Dear AppKitterinos,

I want to make my table view’s header taller so I can use two lines of text in some of my column labels.

I can increase the height of my table view’s header like this:

    CGRect frame = self.tableView.headerView.frame;
    frame.size.height += 14;
    self.tableView.headerView.frame = frame;
    [self.tableView.enclosingScrollView tile];

But when I do so, the header is drawn incorrectly. I have attached screen shots of the incorrect appearance:

- 10.14b4-light.png is the appearance on macOS 10.14 beta 4 in light aqua appearance.
- 10.14b4-dark.png is the appearance on macOS 10.14 beta 4 in dark aqua appearance.
- 10.13.6-sometimes.png is the appearance on macOS 10.13.6. Sometimes the test app looks like this at launch. Other times, it looks like 10.13.6-after-resize.png.
- 10.13.6-after-resize.png is the appearance on macOS 10.13.6 after resizing the window. Sometimes the test app just looks like this at launch, without needing to be resized first.

I have also attached my test project.

Please make NSTableHeaderView draw itself correctly even when I make it taller than normal.

Thanks,
Rob
