That said, my attempt at validation of the fix is met by a
failure to build qt6-qttools version 6.7.0 on NetBSD/amd64
9.99.4.  I thought that would be easy, but not so:

[ 27%] Building CXX object src/linguist/lupdate/CMakeFiles/lupdate.dir/__/shared/projectdescriptionreader.cpp.o
In file included from /usr/pkgsrc/devel/qt6-qttools/work/qttools-everywhere-src-6.7.0/src/assistant/qlitehtml/src/container_qpainter.cpp:5:

   80 |     void draw_background(litehtml::uint_ptr hdc,
      |          ^~~~~~~~~~~~~~~

etc. etc. with similar complicated C++-related errors beyond my
C++ abilities.
