A DESCRIPTION OF THE PROBLEM :
New IME input problems since JDK-8320912 changes.

After applying this change, the IME cannot be typed after the small window is displayed.
Even basic applications that use ContextMenu, ChoiceBox, ComboBox, MenuButton, etc. are affected.
The impact of this problem will be perceived as block level in the IME usage environment.

This problem is no longer reproduced by reverting the changes in JDK-8320912.
However, since JDK-8301900 depends on the changes in JDK-8320912, 8301900 was also reverted.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. launch the test application
2. display a selection list such as ChoiceBox, ComboBox, MenuButton, ContextMenu, etc. and select an item.
Input (Japanese) characters into TextField and TextArea using IME.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
You can enter characters with IME.
ACTUAL -
Cannot input text with IME
