This device specific issue occurs whenever the hitbox for a selection is highlighted from a mouse. Pressing enter will execute the correct function while using the arrow keys to act as a cursor, but shouldn't do this when a mouse is on screen. That being said, this issue is only present when the player is able to use a mouse, and access the in-game items and menu buttons.

An easier representation of this is if a player opens the chat window and holds their mouse over the exit button. The player then types in chat and presses the enter key when finished. Instead of the message being displayed, the click sound will play and the window will close without the message in chat, or in the player's chat history.
