a special public key can't be in key_auths array: Missing Active Authority

The following public key can't be in key_auths array: (I generated with uptick randomwif)

It is very strange that I tested the api for account_update with multi-signature, but if the above public key is in any key_auths array (either owner or active ) it will report the following error:

missing required active authority: Missing Active Authority 

Tested in node and browser , one account each. you can create a new account without asset, then add above active key. Normally it will report fee insufficient issue, but it reports the above issue.

as discussed with @abitmore , this publickey triggers a Serialization issue. Within this public key, the javascript serialization buffer is different from the backend.
