this appears to be macOS native behavior

not every control requests the focus on a click.
i.e. a trackbar doesn't require a focus, while edit does.

To build on what Dmitry said, it looks like if you set TabStop to False for both trackbars, it will act more like macOS behaves with Xcode. In Xcode, I put two trackbars onto a form and ran it and I couldn't get either one of them to show the focus border, even by tabbing.
