Yes, this update causes temp pets to not be targetable as NPCs, but it has a big side-effect; if you have a normal pet up already, the temp pet will take over the F1 pet target as well as cause some bugs with the pet window. This is probably going to have to be reverted until a bug-free solution is written.
Also added this note on the SVN Rev1872 comments:
