Additional context

I noticed an issue with userEvent.paste in the following case.

Nevertheless, in the browser, such code works. After examining the Chromium source code, I confirmed this. Chrome intentionally converts the data type name to lowercase. It seems more appropriate to implement similar logic on the userEvent side.
