Include leading whitespaces in QML TextEdit - c++

Question

I am using a QML TextArea as a text input. It seems like this TextArea automatically removes leading and trailing whitespaces. If I start the text with a couple of spaces, the cursor doesn't move. If I then type a normal character, the cursor jumps the amount of spaces typed before.
I managed to include trailing whitespaces by changing the TextOptions of the underlying QQuickTextDocument on the C++-side, but couldn't find a way to show leading whitespaces.
Is there a way to do that?
EDIT: It's really just a (very slightly styled) TextArea
T.TextArea {
id: control
padding: 6
opacity: enabled ? 1 : 0.8
font.pixelSize: TextStyle.font.size.regular
color: Color.gray_09
selectionColor: Color.cyan_066
selectedTextColor: color
wrapMode: TextEdit.Wrap
InputFieldPlaceholderText {
anchors.top: parent.top
anchors.left: parent.left
anchors.topMargin: parent.topPadding
anchors.leftMargin: parent.leftPadding
textBox: control
}
TextEditFormatter {
id: textAreaFormatter
Component.onCompleted: onCompleted()
}
}
Which I call like this:
Flickable {
anchors.fill: parent
flickableDirection: Flickable.VerticalFlick
TextArea {
id: textArea
anchors.fill: parent
}
}
For Completion: This is what the TextEditFormatter does, but not using it doesn't change the behaviour...:
void TextEditFormatter::onCompleted()
{
auto document = parent()
->property("textDocument")
.value<QQuickTextDocument *>()
->textDocument();
auto textOptions = document->defaultTextOption();
textOptions.setFlags(QTextOption::IncludeTrailingSpaces);
document->setDefaultTextOption(textOptions);
}
