According to build/qt5webengine-5.12.7/config.summary:

  Optional system libraries used:
    re2 .................................. no   ---> not in buildroot
    icu .................................. no   ---> handled by select BR2_PACKAGE_QT5BASE_ICU but not found (version mismatch)?
    libwebp, libwebpmux and libwebpdemux . yes  ---> already handled and fixed by your previous patch
    opus ................................. yes  ---> already handled
    ffmpeg ............................... yes  ---> already handled
    libvpx ............................... yes  ---> already handled
    snappy ............................... yes  ---> handled by our patch
    glib ................................. yes  ---> already handled
    zlib ................................. yes  ---> handled by qt5base
    minizip .............................. no
    libevent ............................. no   ---> handled by our patch
    jsoncpp .............................. no   ---> handled by our patch
    protobuf ............................. no   ---> handled by our patch
    libxml2 and libxslt .................. no   ---> handled by our patch
    lcms2 ................................ no   ---> handled by our patch
    png .................................. yes  ---> handled by qt5base (only in case BR2_PACKAGE_QT5BASE_PNG is set)?
    JPEG ................................. no   ---> handled by qt5base (only in case BR2_PACKAGE_QT5BASE_JPEG is set)? In my config
                                                     BR2_PACKAGE_QT5BASE_JPEG is set but not found?
    harfbuzz ............................. yes  ---> handled by qt5base (only in case BR2_PACKAGE_QT5BASE_HARFBUZZ and BR2_TOOLCHAIN_HAS_SYNC_4 is set)?
    freetype ............................. yes  ---> handled by qt5base

So your patch is definitely an improvement and you can add my

Care to take a look if the buildroot package minizip is sufficient for qt5webengine?

Leaving icu, png, jpeg and harfbuzz for more research....
