static built universal PDF module not properly installed on MacOS

I'm using a statically built universal (x86_64;arm64) version of Qt6.5.3 on MacOS.
During installation of the kit the file qtwebengine/src/pdf/release/Pdf.a doesn't seem to be copied into the $QT_INSTALL_LIBS folder, so linking any qmake project leads to linker errors.
As a workaround I manually copied the file and added $$[QT_INSTALL_LIBS]/Pdf.a to the QMAKE_PRL_LIBS line in $QT_INSTALL_LIBS/libQt6Pdf.pri.
After that the project compiles as expected.
