USE_QT= . . . webengine . . . and libQt5WebEngine.so.5 vs. libQt5WebEngineCore.so.5 dependency failures in builds

[Mark Millard]

First, for reference, showing libQt5WebEngine.so.5 provided
when I tried installing an official one (14.2-RELEASE context):

# pkg info qt5-webengine
qt5-webengine-5.15.18p7_2
. . .
Shared Libs provided:
        libQt5PdfWidgets.so.5
        libQt5WebEngine.so.5
        libQt5WebEngineWidgets.so.5
. . .

And showing that py-qt5-webengine's USE_QT contains:
webengine

# cat /usr/ports/www/py-qt5-webengine/Makefile 

. . .
USES=           gl pyqt:5,dist python qt:5
USE_GL=         gl
USE_PYQT=       pyqt5 qtbuilder:build sip:build
USE_PYTHON=     concurrent flavors
USE_QT=         core declarative gui location network printsupport webchannel \
                webengine widgets qmake:build
. . .

Yet my build experiments get a missing
libQt5WebEngineCore.so.5 dependency
(note the "Core" vs. not):

[00:06:41] [01] [00:00:00] Warning: py311-qt5-webengine-5.15.7 will be rebuilt 
as it misses libQt5WebEngineCore.so.5 which no dependency provides. This may be 
a port bug if it repeats next build.

(The rebuild does not fix the missing
libQt5WebEngineCore.so.5 issue.)
