Is there is a significant amount of HTML editing JavaScript code that would just work with vertical text if not for this one detail? In that case, it might be appropriate to utilize such tricks indeed.

Otherwise, asking authors to make the change from "right" to "forward" appears like a very appropriate thing to ask for, among other things necessary to support vertical text.
