Changing existing custom emojis dont save

Changing custom existing emojis is absolutely impossible in this current version of Rocket.Chat it seems.

Server Setup Information

  • Version 3.9.3 Mongo 3.6.14 Node v12.18.4
  • OS: Ubuntu 18.xx LTS
  • Deployment Method: snap
  • Number of Running Instances: 1
  • DB Replicaset Oplog: Enabled
  • Proxy: nginx

I expect to be able to change existing custom emojis such as changing tag or removing alias.
Pressing the blue save button does nothing.
There is no duplicate emoji name or alias, nor is there any special characters other than a-z and a _ underline.
