QLabel's text is not rendered properly for a LTR string in a RTL layout

For a RTL layout, if a LTR string say "Fully LTR text..." is set to a QLabel and QPushButton, the output for both is different,

    QString ltrOnly("Fully LTR text...");
    ui->labelLTROnly->setText(ltrOnly); ---> Output is "Fully LTR text..."
    ui->pushLTROnly->setText(ltrOnly); ---> Output is "...Fully LTR text"

I think QLabels are not behaving correct here, Please refer to the attached sample, it has another use case with a mixed string.
