QWebEngineView print() with copyCount multiplies number of copies

When printing multiple copies with QWebEngineView::print() (via QPrinter::copyCount) it multiplies the number of copies. I.E. if 2 copies are specified 4 copies print, 3 copies 9 prints, and so on.
This is on 6.3.0 compiled from source on VS2022

I've attached a test case that reproduces this.

Steps to reproduce:
Running the test case, after the webpage loads:
1. Click print
2. Select a printer (if default is not a the desired printer, PDF printers may not allow a quantity greater than 1)
3. Ensure the number of copies is still 2
4. Click Ok

Expected Result:
2 Copies of the website print

Actual Result:
4 Copies of the website print
