[1] This feature was initially implemented in Gecko 47.0 (Firefox 47.0 / Thunderbird 47.0 / SeaMonkey 2.44) behind the preference dom.document.scrollingElement.enabled, defaulting to true on Nightly builds and false otherwise. In Gecko 48.0 (Firefox 48.0 / Thunderbird 48.0 / SeaMonkey 2.45) the feature got enabled by default and the preference removed.
