QStandardItemModel's setItem(int row, QStandardItem *) with row 0 causes the tableView to lose header stretched attribute

Hello there. today I encountered something strange and decided to send it to you to fix.

I am using win10 with Qt 5.10.1 and mingw.

when I try to call setItem(int row ,QStandardItem *); if the row is 0 then the ui->tableView->horizontalHeader()->setSectionResizeMode(QHeaderView::Stretch); will be discarded. this only happens if the row number is 0.

I have also attached a program to show the problem. if you click on 1 there will be no problem but when the 0 button is clicked then the view will not be stretched anymore.

Goodluck
