Combination of 'HangulInputMethod' and 'QGraphicsTextItem' does not work as expected.

We are trying to support CJK (Chinese, Japanese and Korean) input using Qt VKB.
Our applications are C++ applications and not QML.
So we have a hybrid (C++ and QML) application.
We are using QML only for Qt VKB.
However, we have observed that "Combination of 'HangulInputMethod' and 'QGraphicsTextItem' does not work as expected."

You may need to recompile Qt VKB to add all supported languages.

I have added the following code at the start of

"Qt/5.10.1/Src/qtvirtualkeyboard/src/config.pri"

OR

"Qt/5.15.7/Src/qtvirtualkeyboard/src/config.pri"

CONFIG += lang-all
CONFIG += disable-desktop

The EXPECTED behavior is QT_VKB_CJK_QWIDGET_TEST_APP

The INCORRECT behavior is QT_VKB_QGRAPHICS_TEXT_ITEM_TEST_APP
