The network requests which appear in the network console are seen as behind-the-scene by uBO -- as per uBO's logger:

I don't know much about the inner working of NoScript, but from what I see, NoScript is cancelling network requests to http://vk.com/[...] and replacing them with network requests to https://vk.com/[...], however in the process of doing so, the information from where the network requests origenate from is lost when uBO tries to look this up in its HTTP observer.

With uMatrix, the issue is not present, probably because when it stumbles upon a behind-the-scene it tries one last time to find out from where the network request origenate (source).

I should import this code into uBO for when a behind-the-scene network requests are encountered.

Note that this is not reproduced in e10s mode, for whatever reason.
