Comment (by jeremyfelt):

 Until 3.9, we would search for both www and non-www domains, find the
 site, and then let a redirect happen via `redirect_canonical()`. In 3.9,
 we use non-www and www when doing the network search, but not when doing
 the site search. A site is not found and `redirect_canonical()` does not
 happen.

 I attached
 [https://core.trac.wordpress.org/attachment/ticket/27927/27927.diff
 27927.diff], but as I'm writing this up I'm realizing it does not work if
 the multisite install was done for the full www domain. Of course,
 creating a subdomain install on a `www.domain` does seem seem out of the
 ordinary...

 We'll likely need to search for both www and non-www variants in
 `get_site_by_path()` to match previous behavior.
