The spec says "the content attribute must have a value consisting of a valid
BCP 47 language tag" and the empty string (or indeed a string of spaces) is not
a valid language tag according to BCP 47.

The whole use of Content-Language as any kind of hack to work around two bugs
(the lack of support for lang="" and the misinterpretation of HTTP's
Content-Language header) is dubious. Making it two lines instead of three makes
no improvement.

You can "cancel" this misuse of the HTTP header using the lang="" attribute.
