When the first row of a Surface3DSeries contains all NaN, trying to render (default RHI backend on Windows) crashes in (due to Q_ASSERT(isFinite()); in QSSGBounds3::center()) (see stack trace below).
This is easily reproducible using the SurfaceGallery Example (after fixing the missing imports in QML) by changing line #71f in datasource.cpp to
float y = j ? (colWave * ((float(qSin(waveAngleMul * colMod) + 1.0)))) * waveMul + QRandomGenerator::global()->bounded(0.15f) * yRangeMod : std::numeric_limits<float>::quiet_NaN();
so that all data in row 0 is NaN.
This used to work as expected when using Surface3DSeries from QtDataVisualization in Qt 5.15.x.
