Trasition Exit time taken from source state, not destination state

1. What happened
Transistion/State finishes before it's Exit time, taking the source exit time instead :(

2. How we can reproduce it using the example you attached
Open attached project
Open Interrupt_BUG scene
Select mangagirl and open Animator
Click Play in the Editor
Click Con2 parameter...
Transition starts, then jumps back to Idle State.
Click Con2 again, to see the bug... again.
