V0242: Links with the noreferrer keyword do not create a new browsing context

The specification states:

 ... Browsing context names
     ...
     The rules for choosing a browsing context given a browsing context name are as 
     follows. The rules assume that they are being applied in the context of a browsing 
     context, as part of the execution of a task.
         ...
         5.  Otherwise, a new browsing context is being requested, and what happens 
             depends on the user agent's configuration and abilities — it is determined by 
             the rules given for the first applicable option from the following list:
                 ...
                 If the user agent has been configured such that in this instance it will 
                 create a new browsing context, and the browsing context is being 
                 requested as part of following a hyperlink whose link types include the 
                 noreferrer keyword
  
                     A new top-level browsing context must be created. If the given 
                     browsing context name is not _blank, then the new top-level browsing 
                     context's name must be the given browsing context name (otherwise, it 
                     has no name). The chosen browsing context must be this new browsing 
                     context. The creation of such a browsing context is a new start for 
                     session storage.
