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