That a mistake to consider that as a correct behavior even based on the amount of bugs we have.
The MAXIMIZED_BOTH property was considered as a "maximize" action, and should allow such behavior for the custom application when the decorations are rendered by the app. You can check all that bugs and see how many people report it and then accept, for example this one: https://bugs.openjdk.java.net/browse/JDK-4976497 which shows that even Swing is broken if setDefaultLookAndFeelDecorated is used.

Note that this test is not for the borderless window which should cover the full screen but specifically for the MAXIMIZED_BOTH action which expected to maximize the window in the same way as for decorated frame. And I think this is how it works on other platforms since the test passed there. This is why this test created 20 years ago was not changed, it was expected that we fix the JDK.

I suggest to rollback  this and apply the fix to JDK.
