Animator: Selecting transition link that goes to state with high speed can hang Editor

1. Have 2 states with gradual transition from node1 to node2
2. For node2 set speed to a high value (e.g. 1000000)
3. Select transition link between the nodes
---> Inspector will display link settings in few seconds and not immediately.
If bring the speed value to a higher number, the editor might even freeze (or appear to become such).

Reproducible in Unity 5.0 b14
OS: Windows 8.1 x64
