Chat message content can extend past the outline of a button and past the scroll bar

The bug

The content of a long chat message, although shortened using an ellipsis, can still extend outside of the border of its box.

How to reproduce

1. Create a server, and join the server with two accounts
2. From one account, send a very long chat message
3. From one account, navigate to the social interactions screen, and select the icon for the other player
4. Click the "Select Chat Messages to Report" button, and select the long message
   The long chat message and ellipsis extend past the outline
