Aman Agrawal 48addae20b tippyjs: Fix traceback on reaction tooltip. ...

It can happen that reactions are re-rendered while we are
in the process of showing tooltip for them. In that case,
we setup MutationObserver for an element not present in DOM
which results in weird behaviour. We avoid it by checking the
element again before setting up MutationObserver for it.

See https://chat.zulip.org/#narrow/stream/6-frontend/topic
/tippy.20bug/near/1206316 for details on the issue.
