QHeaderView eliding versus font size

When I use a style sheet to define a font-size larger than the default for a QTableWidget's horizontal header, the text gets cropped. This happens regardless of whether I elideLeft, elideMiddle, or elideRight.

Code:

---

QString header_styleSheet = "::section {" // "QHeaderView::section {"
                     "spacing: 1px;"
                     "background-color: orange;"
                     "color: purple;"
                     "border: 1px solid purple;"
                     "margin: 1px;"
                     "font-family: arial;"
                     "font-size: 18px; }";
 
         splitTimes->horizontalHeader()->setStyleSheet(header_styleSheet);

---

Here's what the header looks like with 18 px font:
Attachment 8673

versus a 12 px font:
Attachment 8672

It's like the eliding code isn't aware of the font-size that was applied with the stylesheet.

I saw the same type of thing for horizontalHeader()->setResizeMode(QHeaderView::ResizeToContents);

Is there something I need to do to change the horizontal header font size other that using a style sheet to avoid this?

Thanks,
