Can't add token with a Symbol longer than 6 charachters

[jamiehewitt15]

Describe the bug
When attempting to add a token that has a symbol length of more than 6 characters I am getting the following error message in the console:

MetaMask - RPC Error: Invalid symbol "QUICRA-0": longer than 6 characters. 

Steps to reproduce
Steps to reproduce the error:

1. Go to https://market-git-issue-549-token-length-oceanprotocol.vercel.app/asset/did:op:7Bce67697eD2858d0683c631DdE7Af823b7eea38
2. Click 'Connect Wallet' and select metamask
3. Once metamask is connected, click on 'ADD QUICRA-0 TO WALLET'
4. Open the console
5. See error

Expected behavior
To my understanding it should be possible to add custom tokens with symbols up to 12 characters long.
This was implemented here: #5816
And appears to still be implemented here:

metamask-extension/ui/pages/add-token/add-token.component.js

Line 206 in bc24d9e

if (symbolLength <= 0 || symbolLength >= 12) {

Browser details (please complete the following information):

• OS: Ubuntu
• Browser: Firefox Browser 88.0 (64-bit)]
• MetaMask Version 9.4.0

I'm also experiencing the same issue on Chrome with MetaMask Version 9.4.0

Closed, #10670 has been merged.

@tmashuang I'm using Metamask 9.4.0 (which is the latest) and it's still giving me the Invalid symbol "QUICRA-0": longer than 6 characters. error. Do you know when #10670 will be released?
