If a document in a background tab calls window.prompt() then the call to prompt() will return immediately, and no dialog will be shown to the user for that call to prompt(). If the tab is foremost (if it is the active tab in the front window), then the call will show a dialog. Specifically, this removes the ability to use window.prompt() to bring a tab to the front against the user’s will.
