I think this issue results from a misunderstanding.

The truncation in question here is the result of authenticators blindly truncating these fields at a given byte length. Since the language tag is at the end, such truncation could transform a language tag into another language, like the Klingon to Tagalog change that you note. The fact that a directionality marker or CANCEL TAG always follows the language allows for an implementation to be aware that truncation occurred and thus potentially ignore the language tag.
