Ignite doing more than double its max damage

The link is a video to me being caught out and getting fucked by yasuo. but a little after the fight, you can see i open the death recap and see that ignite did much more damage than it should have. Is this just a bug in the deathrecap? or did ignite actually do more than it was supposed? Could be the yasuo player was actually cheating, but i doubt that. most likely its just a bug in deathrecap saying it did more damage with something to do with me having guardian angel, it could be that the death recap thought ignite kept doing damage after i had already died and started coming back thanks to GA. who knows, i just hope it gets fixed too.
