Description Doran Moppert 2018-05-09 03:16:40 EDT 
If a URL using the `file:` protocol is dragged and dropped onto an open tab that is running in a different child process the tab will open a local file corresponding to the dropped URL, contrary to policy. One way to make the target tab open more reliably in a separate process is to open it with the `noopener` keyword.
