Open any document. Single click somewhere within that document. What do you expect to happen? Do you expect your cursor to be placed where you clicked, or do you expect the entire line to be highlighted? My guess is that you expect consistency in every application doing the same thing for a single click.
Just because one browser decided to change how they react, and everybody else copied that behavior, does not mean it is the correct or expected behavior. You’ve just gotten used to the difference that was forced on you, but imagine if every application on your desktop reacted differently depending on how many times you clicked a spot? What happens when they also start modifying the results of a right-click into something unexpected like clearing your cookies? Is that also OK just because one browser started doing it and every other browser copied that function?
