When removing a few words from the beginning of some piece of text, the edit diff also incorrectly flags the first word that didn't actually change.

For example, when changing "The Only Michael - Someone Else's Fur" to "Someone Else's Fur", then the diff tool also highlights "Someone" in both versions, although it didn't change.
