• In Firefox, sources are seen in resources-available-array of type network-event, source
  • See also console-message, if there were any past console messages
• We can send existing sources in resources-available-array for source (see watcher.js:531)
• But client never requests them in watchResources for source despite firefox.js:84
  • Tried setting sources to true in RootActor traits
  • Tried setting source to true in SessionContext supported_resources
  • Maybe need to send empty resources-available-array for console-message and error-message? Servo currently just ignores those watchResources requests, the internal BrowsingContextActor::resource_available takes and sends exactly one resource

Other TODO's:

• devtools: improve ID naming for better readability and context #35942
• devtools: Use webview_id as browser_id #35956
