I have manually added a JMenuBar to the frame in `bug4624207.java` and ran the test with both "apple.laf.useScreenMenuBar" set to true/false. In both cases, the test still fails.

I have looked further into whether macOS officially supports mnemonics, and there are a few occurrences (as you've given examples of some) where mnemonics work, but there seems to be no official documentation that I can find that confirms that this is supported. As such, I believe this change can continue as-is for now.
