clarify UX: reaction modal 'X' button in easily misused spot

See image: http://prntscr.com/ofszve When one has rights to remove reactions from a message, the 'X' button appears on the right side on mouseover. However, when you mouse over it on the first entry, the X button appears where one would expect the "exit" 'X' button to be, and it becomes very easy to accidentally delete the reaction rather than close the modal Please clarify the user experience to reduce occurance of this issue Fast Suggestion: change it to a button labeled 'Remove' or 'Delete' or a trashcan icon
