The bug

When playing Minecraft at a small enough resolution that makes the Select Report Category menu unable to be displayed without a scroll bar, the scroll bar that is presented intersects with the outline of the selected category.

How to reproduce

1. Create a server, and join the server with two accounts
2. From one account, navigate to the social interactions screen, and select the icon for the other player
3. Click the Select Report Category button, and select any category option
   The option's outline intersects the scroll bar
