Right now, the spec defines two overloads for scrollIntoView(): one with no arguments, and one with a boolean arg and a ScrollOptions arg. This means that if you want to specify any scroll options, you must provide an opaque boolean value. Boolean args are an anti-pattern that we don't do today, but of course this is a legacy part of the API. If we were designing this from scratch, this would just be part of the ScrollOptions dict. I propose we add a third overload that takes just a ScrollOptions dict, for when you don't want to control the top/bottom behavior and don't want to supply an opaque dummy bool. If no one's implemented the current ScrollOptions overload yet, then I also propose we drop that overload entirely, and add an "align" attribute to ScrollOptions that takes "top" or "bottom" (or maybe a "top" attribute that takes a bool, whatever). That way you either call the function with the legacy boolean arg, or with the modern dict arg, not both. ~TJ
