English words are not in the correct order when mixed with Arabic and splitted to multiple lines

[HasanAlqaisi]

Describe the bug

When we mix Arabic and English words, the order of the English words is not correct when they split into multiple lines

To reproduce

  Future<Uint8List> _generatePdf(PdfPageFormat format, String title) async {
    final pdf = pw.Document(version: PdfVersion.pdf_1_5);
    final fontStyle = pw.TextStyle(
      fontSize: 50,
      fontWeight: pw.FontWeight.bold,
      font: await PdfGoogleFonts.iBMPlexSansArabicRegular(),
    );
    pdf.addPage(
      pw.Page(
        pageFormat: format,
        build: (context) {
          return pw.Text(
            'قررت أن أقوم برحلة استكشافية إلى the historical old town',
            style: fontStyle,
            textDirection: pw.TextDirection.rtl,
          );
        },
      ),
    );

    return pdf.save();
  }

Nope, I am not using it in projects right now so I don't know if there are any workarounds.
