QTextDocument: calling setTextWidth(-1) breaks RTL text alignment

    QTextDocument doc;
    doc.documentLayout(); // create default doc layout
    doc.setPlainText("טֶקסט\nשדגשגשגשגדוגמא\nטֶקסט");
    doc.setTextWidth(-1);

    QRectF firstLineRect;
    for (auto block = doc.begin(); block != doc.end(); block = block.next()) {
        auto *blockLayout = block.layout();
        for (int i = 0; i < blockLayout->lineCount(); ++i) {
            const auto textLine = blockLayout->lineAt(i);
            if (firstLineRect.isNull()) {
                firstLineRect = textLine.rect();
            } else {
                Q_ASSERT(qFuzzyCompare(textLine.rect().right(), firstLineRect.right()));
            }
        }
    }
