Before this commit, clicking on an item from the
emoji menu of a composer was not putting the emoji
in the input.
Steps to reproduce:
- Open discuss app
- Select a conversation with a composer
- click on emoji menu in the right-side of the composer
- click on an emoji in the emoji menu
> the emoji has not been put in the input of the composer
This problem was caused by a race condition with the event
`focusout` on the emoji button and the `click` on an emoji
item. `focusout` always happens before `click`, and `click`
event following a `focusout` event can only happen when the
element is visible. This was not the case, because the emoji
container is removed from the `focusout`, so no `click` is
triggered on the emoji item.
This commit fixes the issue by listening on `mousedown` on
the emoji item instead of `click`, which is triggered before
`focusout`.
