Self-XSS in posts by formatting text as code

Hi I have found an XSS in Slack. To reproduce the issue, just follow this: 1. Go to your Slack account (accountname.slack.com) 2. Below you will see a plus (+) sign, click that, there will be three options, click "Create Post" 3. You will be redirected to a page where you will create it. 4. Type the payload. I used: <svg onload=alert(domain)>. then Highlight it.. on the left side, there are symbols... click it and choose this symbol: ( <>) which is for code.. 5.
