IIS10 not handling HTTP/2 requests properly

We are facing issues in serving some types of HTTP/2 requests when Jakarta ISAPI Redirector is being used with IIS.
Current Case: '*.cfm' are mapped to be served by the Jakarta ISAPI Redirector.
When we try to serve 'index.cfm' in the browser, two different types of behaviours occur
Now to rule out the possibility of any issues that the ISAPI Redirector may be causing, we tried writing back to the browser as soon as the code flow comes to the mod_jk's code. But it fails even then. The API being used was:
BOOL (WINAPI * WriteClient) ( HCONN ConnID,
DWORD dwReserved );
A video explaining this in details has been posted by Giancarlo Gomez, on YouTube. The video can be found here: Video Link.

If you believe this is a bug then you should open a support case with Microsoft.
A lot of variables here. Different browsers configurations of HTTP2, implementations of custom modules, etc with a niche technology, etc
It is unlikely you will get any answers here. Very little experience of the API is here. A support case it the way forward.
