Currently, Ctrl++ toggles the location bar between editable and breadcrumb modes, which is nice. However, it does this even when the URL bar is not focused, which can lead to times when you want to enter a path and instead accidentally make it un-editable, oops.
This patch refines the behavior so that it only toggles the mode when the location bar has focus and everything is selected. This brings the behavior into 100% consistency with Dolphin, once D16980 lands.
