To improve the user experience of the InlineEngagement component we are updating the clicking behavior for our reaction pills. Before whenever a user would click on a reaction, the MessageReactionsModal would pop up, but now if a user clicks a reaction pill they will react/unreact to that message depending on whether or not they have already reacted to that message already. To view the MessageReactionsModal the user now needs to hover on the reaction pill and click on the popup (a similar pattern with other chat apps such as discord and slack), and that functionality will be handled in subsequent diffs
Depends on D8807
