When using USA International Keyboard Layout, and we want to wrap a selected text into quotes, the first quote overwrites the selected text.

Set your keyboard layout to USA International, then write something into Sublime Text 2, select it, and type a quote (wanting to wrap selected text into quotes). The "pre-quote" overwrites selected text. This "pre-quote" is a state of waiting until a vowel or spacebar be pressed, in order to know which character is user wanting to type.
