[Issue] Domain Fronting - Grunt SNI points to Host header instead of ConnectAddress

I'm looking to set up an HTTPS listener with a TLS certificate , but the SSLCertificate doesn't seem to be handled properly. I see in docs it expects a pfx file, but it doesn't actually upload when the POST is sent to create the listener (just the filename). When the form returns with the SSLCertificate error, and I resubmit the form, a key constraint error is thrown resulting in a 500 error.

Screenshots and details below.
