In Firefox 3.6 and later this function is now case-sensitive so that a query for "foo" will only match "foo" and not "Foo". For more background on this, please see the comment from Henri Sivonen about the change.

api.Element.scrollHeight πŸ“‹Chrome12/11/2008 Edge7/29/20152421
Firefox: Before Firefox 21, when an element's content does not generate a vertical scrollbar, then its scrollHeight property is equal to its clientHeight property. This can mean either the content is too short to require a scrollbar or that the element has a CSS style overflow value of visible (non-scrollable).Firefox for Android: Before Firefox for Android 21, when an element's content does not generate a vertical scrollbar, then its scrollHeight property is equal to its clientHeight property. This can mean either the content is too short to require a scrollbar or that the element has a CSS style overflow value of visible (non-scrollable).Internet Explorer: In Internet Explorer 5 through 7, if padding is set, the value of scrollHeight is equal to the sum of the top and bottom padding. This behavior was fixed in Internet Explorer 8.

Internet Explorer: On Internet Explorer 6 through 8, the event model is different. Event listeners are attached with the non-standard EventTarget.attachEvent method. In this model, there is no equivalent to event.currentTarget and this is the global object. One solution to emulate the event.currentTarget feature is to wrap your handler in a function calling the handler using Function.prototype.call with the element as a first argument. This way, this will be the expected value.
