” it’s a bit more complicated since the Glorious Revolution enshrined the principle that ultimately sovereignty rests not with the Sovereign or the Crown but with Parliament”
That isn’t completely accurate. The taxing power was already with Parliament rather than the monarch before the “Glorious Revolution” (which was anything but glorious for Catholics). OTOH the monarch even today as in theory a right of veto of any law passed by parliament, with no override possibility. However, the last time that veto was used (withholding of royal assent) was in 1708. But even that is complicated. One of the things that contributed to the American Revolution was that colonial governors appointed by the monarch continued to veto acts of colonial legislatures. And one of the specific grievances against King George III listed in the Declaration of Independence was the failure to set up any kind of democracy at all in Quebec after it had been annexed by Great Britain in 1763.
