Experiment with hiding <script>'s 'nonce' content attribute.

third_party/WebKit/LayoutTests/W3CImportExpectations

 # This file controls which subdirectories of the w3c test repos we do (or don't) import.
 #
 # This file acts as a blacklist; directories and files not listed here will automatically
 # be found and imported.
 
 # When removing blacklist entries:
 # * Comment out the line rather than deleting it, to show it is intentional
 # * Change [ Skip ] to [ Pass ]
 # * Add a leading comment: ## Owners: user@example.com
