Text elide in QTableView is incorrect.

main.c++ which will reproduce the bug:

#include <QApplication>

#include <QTableView>

#include <QHeaderView>

int main(int argc, char** argv)

{

    QApplication app(argc, argv);

    auto* view = new QTableView;

    class Model: public QAbstractItemModel {

    public:

        QModelIndex index(int row, int col, const QModelIndex& index) const override

        {

            if (!index.isValid() && row == col && row == 0) return createIndex(0, 0);

            return {};

        }

        QModelIndex parent(const QModelIndex& index) const override { return {};}

        int rowCount(const QModelIndex& parent) const override

        {              if (!parent.isValid()) return 1;              else return 0;         }

        int columnCount(const QModelIndex& parent) const override
        {            if (!parent.isValid()) return 1;           else return 0;        }
        QVariant data(const QModelIndex& index, int role) const override

        {

            if (role == Qt::DisplayRole && index.isValid())

                return tr("The data of items in models are assigned an ItemDataRole;"

                          "each item can store a QVariant for each role.");

            return {};

        }

    };

    

    view->setTextElideMode(Qt::ElideMiddle);

    view->horizontalHeader()->setSectionResizeMode(QHeaderView::Stretch);

    view->setModel(new Model);

    view->show();

    return app.exec();

}

The text may display in the cell:

The data of i...s in models ...

The data of items in ...

The ellipsis always appear at right if space is unavailable, and ellipsis at middle may not appear.
