RFR: 8273573: [macos12] ActionListenerCalledTwiceTest.java fails on macOS 12

[Alexander Zvegintsev]

This test was failing consistently on same machines and at the same time as #8532.

Test failure is also no longer reproducible after #8320 fix.

This is macOS only test, so corresponding `@requires os.family` tag was added. Testing is green.
