RFR: 8313633: [macOS] java/awt/dnd/NextDropActionTest/NextDropActionTest.java fails with java.lang.RuntimeException: wrong next drop action!

[Damon Nguyen]

Test fails intermittently on macosx-aarch64. Adding a delay between the first and second drag fixes the issue since there may be some timing issue between the two drag events. Tested the change twice, with 100 repeats per test on all OS's. All tests passed. Also corrected a spelling mistake and added logical newlines to read/debug cleaner.
