Name collision with br(azilian) language on php-fpm?

[maniac0s]

For some reason I need to remove Brazilian language from mime.conf when using brotli.so with php-fpm so it doesn't get send as content-language br

When I have in my mime.conf:
AddLanguage .br

And add br compression for .css to Drupal, I get the following response headers for the aggregated .css (and only the headers that are aggregated by php in Drupal):

accept-ranges: bytes
cache-control: max-age=31449600, no-transform, public, immutable
content-encoding: br
content-language: br
content-length: 1891
content-type: text/css

server: Apache
status: 200
vary: Accept-Encoding

when I add RemoveLanguage br to mime.config, the content-language header field disappears.

The encoding works however it doesn't seem to make sense to have a content-language br for css files just because I deliver brotli.
