Confirmed - Your XP bar stays at the same % when you Grant Levels.
I have a level 25 druid that i have been granting levels to from 1 from my 3x Mage team and I thought about this same thing the other night but I just though that i had gained XP on the druid from being summoned and discovery XP. I read this and decied to confim it. Here are my results
