    Bug 1658881 - When failing to create a channel and an image request, make sure to set the image blocking status appropriately. r=tnikkel
    
    This is the same status as we do for known no-data protocols here:
    
      https://searchfox.org/mozilla-central/rev/ac142717cc067d875e83e4b1316f004f6e063a46/dom/base/nsNoDataProtocolContentPolicy.cpp#59
    
    This ensures we treat these two cases the same.
