Validator's avatar doesn't appear after changing the validator's identity

[Vahhhh]

If one creates the validator without identity and adds it later with the edit command - the identity is added, but the avatar doesn't change (though the link to the identity appears)

and so on...
All of them has the identity (link to Keybase id with avatar), but no avatar appeared at the block explorer.
