Thank you for your test. I'm not able to reproduce the issue on macOS, but this is the exact bug we are targeting with the proposed fix. The 'i' key typed event is not being consumed, which is why it appears in the log of your test:
`Test: character typed after mnemonic key press: i 
`
I will run the test in a loop on a local mac host with Aqua L&F and see if I can reproduce it. In the meantime, could you please confirm whether the proposed fix resolves the issue on macOS, since you're able to reproduce it there?

KR,
