Some tests fail intermittently in the CI, but not locally(except the FrameSetMinimumSizeTest).

java/awt/Focus/ClearLwQueueBreakTest/ClearLwQueueBreakTest.java
java/awt/Focus/NonFocusableBlockedOwnerTest/NonFocusableBlockedOwnerTest.java
java/awt/dnd/FileListBetweenJVMsTest/FileListBetweenJVMsTest.java
java/awt/Frame/FrameSetMinimumSizeTest.java
java/awt/MouseInfo/ContainerResizeMousePositionTest.java
java/awt/List/ActionAfterRemove/ActionAfterRemove.java
java/awt/LightweightComponent/MultipleAddNotifyTest/MultipleAddNotifyTest.java
javax/swing/JProgressBar/8015748/JProgressBarOrientationRobotTest.java
javax/swing/JTableHeader/6889007/bug6889007.java
javax/swing/plaf/synth/7158712/bug7158712.java


FrameSetMinimumSizeTest fails locally, it calls setVisible, and a lot of setSize on a single EDT call block, and immediately checks that size, but this doesn't behave well on XWayland. The window just doesn't appear on the screen.

So some test stabilization is needed.
