           Summary: urlmon:protocol - The "http protocol from urlmon" test
                    sometimes gets unexpected BSCF_FIRSTDATANOTIFICATION
                    on Windows
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Windows
            Status: NEW

urlmon:protocol - The "http protocol from urlmon" test sometimes gets
unexpected BSCF_FIRSTDATANOTIFICATION on Windows:

protocol.c:3557: Testing http protocol (not from urlmon)...
protocol.c:1122: Test failed: grcfBSCF = 00000001
protocol.c:3561: Testing http protocol (from urlmon)...

See https://test.winehq.org/data/patterns.html#urlmon:protocol

Where:
  00000001 == BSCF_FIRSTDATANOTIFICATION

This happens a bit over once per month on average but with sometimes month-wide
gaps. This also impacts all Windows versions, from Windows 7 to Windows 11.
