glitching into other peoples champions tab (client) 6.22

i sometimes have some internetprobs and this time i was looking at my friends profile, when mine internet broke. i went to mine own profile looked at the champions tab and then i saw that i was lvl 7 ezreal. i could see how many mastery points he had but not which champs he owned, i saw my own champs.

how it happened

1. look at someones profile
2. destroy your internet / airplane mode for lazy people.
3. go to your own profile and go to the champions tab
4. see that your friend has played urgot.

reproducing is easy, 10 out of 10. only problem is clicking away pop-ups.
