response.headers allways return text/turtle with CSS v7.0.2 and rdflib@2.2.33

CSS v7.0.2 :

• mashlib@1.8.8 with rdflib@2.2.30 return the correct contentType on response.headers.get('content-type')
• while mashlib build with rdflib@2.2.33 allways return text/turtle

HumanPane found the correct contentType with :

I finally used a different solution, removing the options parameter in fetcher.webOperation for GET and HEAD
There seem to be a change to investigate in rdflib between version 2.2.30 and 2.2.33.

const response = await fetcher.webOperation('HEAD', subject.uri) // , defaultFetchHeaders())

This is the first time I encounter a difference between NSS and CSS related to rdflib.
