QTextEdit::createStandardContextMenu(QPoint) inconsistency

QTextEdit::createStandardContextMenu(QPoint) takes the coordinates in document coordinates which is completely inconsistent:

• no other function takes a point in document coordinates (e.g. anchorAt(), cursorForPosition())
• there is no public api to get the document coordinates from the QTextEdit

The only workaround which emulates the anchorAt/cursorForPosition behavior is

void MainWindow::OnShowContextMenu(const QPoint& pos)
{
    QPoint p = pos + QPoint(ui->textBrowser->horizontalScrollBar()->value(), ui->textBrowser->verticalScrollBar()->value());
    QMenu* menu = ui->textBrowser->createStandardContextMenu(p);
   ...

I see two options here:

• break SC in Qt6 and syn it with the other functions
• document this strange behavior and live with it until Qt7
