User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:27.0) Gecko/20100101 Firefox/27.0 (Beta/Release)

Steps to reproduce:

I used the momentum based scrolling on OS X on my touchpad on a page to scroll to the top on a page.

As I hit the top, I pressed `backspace` to to back to the previous page which was left somewhere on the half page.

Actual results:

The page I navigated back to, started scrolling at the top.

Expected results:

The page I navigated back to, should not have scrolled at all as the scroll motion was intended for the other page.

Either hitting top or going back should have stopped the momentum based scroll motion. Instead right now it just eventually approaches zero.

Once more thing that should be added: the momentum is also not stopped when the space key is pressed which leaves a weird user experience.

This same behavior happens in Safari using the CMND+[ back command, i.e. scrolling continues on previous page.  Possibly a behavior of Mac OS, not Firefox?  Does is happen in other Mac applications?

I can duplicate this in Safari and in Firefox but not in another Mac application, Preview.
