That font was released more than a year ago, and the Unicode
formatting characters for the hieroglyphs are relatively new, as you
see from the standard's description. So it could be the fonts didn't
yet catch up.
In any case, I'd be very surprised to learn that the Unicode Standard
is so wrong. They have specialists aboard as well.

Like I said: the new way of formatting this script is not yet
supported widely enough. There was a discussion on the HarfBuzz forum
about a year ago, from which I understood that these controls are not
yet supported by fonts.

Why not? And it isn't supposed to be a quadrat, AFAIU, anyway.

AFAIU, U+13431 is the joiner to be used in that case.
And you didn't answer my question: does LibreOffice with the Aegyptus
font display those sequences correctly?
