<Swing Dev> [14] Review Request: 7124307 JSpinner and changing value by mouse

[Sergey Bylokhov]

Hello.
Please review the fix for JDK 14.

Bug: https://bugs.openjdk.java.net/browse/JDK-7124307
Fix: http://cr.openjdk.java.net/~serb/7124307/webrev.00

The bug which was fixed on win/lin long time ago[1] was found by the related
test on macOS+Aqua L&F, the root cause and the fix are exactly the same[2].

The test is moved to the open repo(I have added a loop to check all installed L&Fs), mach5 is green.
