Tested with the mesmer character with these two skills:
1) Combo field – Temporal Curtain

2) Leap finisher – Phase Retreat

If you stand ‘on’ the combo field ‘temporal curtain’ and execute the leap, then you get the combo effect (retaliation).
But if you leap through the field, with the phaze retreat teleport skill, then you do not get the effect.
Is this intended? Or is it a bug.
