I also grew up in the UK, and yes people do, what are you talking about? Here is the Standard calling her one of the Queens of England. It does later point out that she was technically the Queen of the United Kingdom, but the headline is content to use the Queen of England shorthand: https://www.standard.co.uk/news/royals/all-queens-england-how-long-reigned-b1024447.html https://www.standard.co.uk/news/royals/all-queens-england-ho... Here is an article from the Sun that directly refers to her as the Queen of England without any sort of correction whatsoever: https://www.thesun.co.uk/news/3352901/queen-elizabeth-birthday-how-old/ https://www.thesun.co.uk/news/3352901/queen-elizabeth-birthd... Most people would simply say "The Queen" without clarification, but if you're going to say what she was the queen of, I suspect a lot more people would say the phrase "The Queen of England" than "The Queen of the United Kingdom", simply because the former phrase rolls off the tongue more, and we're all used to learning about the kings and queens of England in history or from those rulers sold at gift shops.
