Comment (by mcs):

 r=mcs
 The patch looks good to me. Nice find by both of you! Unlike some truly
 speculative connects such as in response to someone hovering over a link
 with their mouse, this one is not speculative in the same way (because a
 network connection is going to happen soon anyway). That is probably why
 the change that added this "speculative" connect did not raise any red
 flags for Kathy and me when we reviewed the undocumented FF57 bugs (see
 https://bugzilla.mozilla.org/show_bug.cgi?id=1383299).
