404 response when sending a chunked encoded HTTP request to ../oauth2/v2.0/token endpoint

Hello,

When calling the 

oauth2/v2.0/token endpoint

for example like so

https://login.microsoftonline.com/<tenant_id>/oauth2/v2.0/token

with chunked http encoding, so with the following header set

Transfer-Encoding: chunked

I get a 404 response. Is this a known issue?

When I turn off "Chunked transfer encoding" everything works fine and I get a 200 response with the expected tokens.
