Removing Initial Reactions by Spamming

Yesterday just before the logo and looks update, I noticed that when a message has reactions with only 1  reactor per reaction, that spam clicking any of the single reactions enough would delete the initial reaction. After testing with a friend in a server and normal chat, we concluded that the initial reaction could be removed permanently for both sides, client, and server. After further testing today, it seems that the initial reaction is not removed on the client end of the spam reactor, but is removed on the server end for all others. I am familiar with spamming reactions too fast and too often causing a API Block, but no such thing happens in this instance. The initial reaction simply gets removed on the server side but not the spammers client side, with no other effect.
