Chrome's netlogs shwoing "is_preconnect=false" for resource request even after using "preconnect" resource hint for that resource

Question

I am using the "preconnect" resource hints in my site for the font's api as

<link rel="preconnect" crossorigin href="https://fonts.gstatic.com" />

However when i am checking waterfall analysis in chrome devtools, the DNS lookup and SSL connections for https://fonts.gstatic.com/s/roboto/v20/KFOmCnqEu92Fr1Mu4mxKKTU1Kg.woff2 at the time of fetching.

When I checked the netlogs in netlog-viewer.appspot.com, the HTTP_STREAM_JOB_CONTROLLER gives me this result:

https://fonts.gstatic.com/s/roboto/v20/KFOmCnqEu92Fr1Mu4mxKKTU1Kg.woff2

t=9003 [st=  0] +HTTP_STREAM_JOB_CONTROLLER  [dt=123]
                 --> is_preconnect = false
                 --> url = "https://fonts.gstatic.com/s/roboto/v20/KFOmCnqEu92Fr1Mu4mxKKTU1Kg.woff2"

                     --> pac_string = "DIRECT"
t=9003 [st=  0]   -PROXY_RESOLUTION_SERVICE
t=9003 [st=  0]    HTTP_STREAM_JOB_CONTROLLER_PROXY_SERVER_RESOLVED
                   --> proxy_server = "DIRECT"
t=9003 [st=  0]    HTTP_STREAM_REQUEST_STARTED_JOB
                   --> source_dependency = 3234 (HTTP_STREAM_JOB)
t=9126 [st=123] -HTTP_STREAM_JOB_CONTROLLER

Why is it showing is_preconnect false?
