Using cursor keys to navigate LHS causes many items to be placed in history stack

[alexanderdickson]

To reproduce, have a bunch of items in LHS and hold down bottom cursor key.

You can watch the URLs fly by in the address bar, as well as the back button now going through each one.

It'd be better to debounce this "navigate" action, so you can hold down a cursor key to jump a number of items without adding them to your history stack.
