I seem to remember that when I didn't add those "lang=" entries to the html line, my dictionary defaulted to American English. Inside the editor, checking Edit > Preferences > Editor Settings > Manage Spelling Dictionaries, I confirmed that my default dictionary for English is United States. According to the bottom of the blurb to the right of the dictionaries: "When a book specifies its language as a plain language, without any country variant, the default variant you choose here will be used."
Is your default English dictionary still the United States one?
