QAbstractButton RightToLeft text behavior

TBSeb

Hi everyone, i'm using Qt 5.4.0, and i'm surprised by a behavior.

here's a simple code:
qApp->setLayoutDirection(Qt::RightToLeft);
ui->label->setText(tr("-20"));
ui->pushButton->setText(tr("-20"));

And here is the display result:

Does anyone knows something about this special abstractButton setText behavior?

(my wish is to obtain the label behavior)

Thank you for the hint. I filed a bugreport, QTBUG-59807.
