What is the expected behavior?

What went wrong?
Right now to find out (in theory) if something has an overflow you have to do something like "target.scrollHeight > target.clientHeight". First of all that doesn't work all the time, as you can see the scrollHeight is sometimes incorrect (something to fix as well) https://bugs.chromium.org/p/chromium/issues/detail?id=34224
But also, it's something the browser knows about, because it knows when to show a scrollbar or not, it should be a property of the element. Something like element.overflowed or similar. It would greatly improve dealing with development that involves this.

Did this work before? N/A 

Does this work in other browsers? N/A
