Games : Clan perks update question

Let's say your clan is at least level 5, which gives them a perk that increases the level of donated troops, and the troops that was donated is of the maximum level possible for that troop (ie. a Level 7 Giant), what would happen to its level?

Would it:

1. Become level "8" (since Level 5's perk only increases the troop by 1 level) or,


2. Stay at the maximum Level 7 (for the case of a giant)?
