Reactions from FluffyChat aren't propogated

[TheBlueMatt]

I'm honestly not sure if this is a FluffyChat bug or an imessage bug, but any reactions from FluffyChat show a Ignoring reaction $..... due to unknown m.relates_to data error in the bridge, but show up fine on other clients. Reactions from other clients work fine.

Discussion in the FluffyChat matrix room:

<tulir>: fluffychat definitely does reactions wrong, but I'm not sure how wrong it is exactly
<Nico>: It encrypts them
<Nico>: Which is not really wrong
<tulir>: it is really wrong
<Nico>: Why? :D
<Nico>: You are just supposed to send the relation in plain text
<tulir>: what's the point in encrypting an empty object?
<Sorunome ⚡️ Lucky Skies>: nothing says you can't do that
<Sorunome ⚡️ Lucky Skies>: so it's not wrong xP

Reactions aren't getting propagated from Element either. I can see the reaction in FluffyChat and Element, but not in iMessage (and of course, the recipient never see the reaction either)
