Steps to reproduce

For timestamps:

1. Create a message with the following request:

   {
     "embeds": [
       {
         "fields": [
           {
             "inline": true,
             "name": "Test",
             "value": "<t:1771792416>"
           },
           {
             "inline": true,
             "name": "Test",
             "value": "<t:1771792416>"
           },
           {
             "inline": true,
             "name": "Test",
             "value": "<t:1771792416>"
           }
         ]
       }
     ]
   }
   

2. See the issue.

For roles:

1. Create a role named "VERY LONG ROLE NAME TESTING".
2. Create an embed with 3 inline fields as shown above. Replace the "value" keys with a mention of a role created in the previous step.
