We also discovered a compatibility issue with the text/html type: we always wrap text/html data in HTML tags when copying, even if the data is an empty string. In contrast, Chrome ignores the empty string entirely, and Safari simply writes the empty string to the clipboard without wrapping it. (See bug 1967510 comment 11 for details.)

Since we don't ignore empty strings for the text/plain type, I think it makes more sense not to ignore them for the text/html type either, for consistency. Instead, we should follow Safari's behavior and write the empty string without wrapping it in HTML tags.
