[GAMEPLAY] Infinite Braum Passive

Some friends and I found a bug with Braum's passive where, after gaining 2+ stacks and being allowed to wear off, it can be made to reappear again with an ally's basic attacks.

Example:

1. Braum uses his Q to place Concussive Blows on enemy.

2. Ally attacks enemy twice, then four seconds later, Concussive Blows falls off as normal.

3. However, if an ally attacks the enemy again within a couple of seconds, the Concussive Blows indicator will reappear with one stack and behave as normal (including stun).

4. This can be repeatedly indefinitely, as long as the stun doesn't get activated.

Here is a .gif of the issue (apologies for the size)

The bug occurs 100% of the time with these steps. I'm not sure what the time limit for the reactivation is, but it seems pretty long.
