[BUG] Japanese IME Candidate Window overlaps text when typing.（Windows）

[kurogk]

Expected behaviour

When inputting Japanese, the IME candidate window does not overlap with the text.

Actual behaviour

The IME candidate window overlaps by almost half, making it difficult to see the text being input.

Steps to reproduce

Steps to reproduce the behavior:

1. Open the edit screen
2. Enable the Japanese IME
3. Start inputting

Workaround

I added ViewportMargins to QRectF of CursorQuery, thinking that ViewportMargins might not be reflected.

QOwnNotes_IME.CANDIDATE.mp4

Workaround code:

QVariant QOwnNotesMarkdownTextEdit::inputMethodQuery(Qt::InputMethodQuery property) const {
    QVariant result = QPlainTextEdit::inputMethodQuery(property);
    const bool isCursorQuery = (property == Qt::ImCursorRectangle || property == Qt::ImAnchorRectangle);
    if (isCursorQuery) {
        const QMargins vm = viewportMargins();
        const QPoint offset(vm.left(), vm.top());
        if (!offset.isNull()) {
            if (result.userType() == QMetaType::QRectF) {
                QRectF rect = result.toRectF().translated(0, qreal(offset.y()));
                result = rect;
            }
        }
    }

    return result;
}

Probably only in Qt for Windows environments.

Must be an issue with the QPlainTextEdit on Windows with IME. ️🤷🏻
Then I'll try a blind fix (since I can't reproduce that)...

26.5.1

• Fixed IME candidate window overlapping text when typing with a Japanese (or
  other CJK) IME on Windows by overriding inputMethodQuery() in
  QOwnNotesMarkdownTextEdit to offset the reported cursor rectangle by the
  current viewport margins (for #3590)

There now is a new release, could you please test it and report if it works for you?
