Show emoji reactions in a closed thread

Follow-up from !1851 (merged)

What does this MR do?

When a thread is closed it is not possible to give emoji reactions. However, the previously given emojis should still be visible. This MR makes them visible.

How confident are you it won't break things if deployed?

Very sure
