This is pretty odd - it seems that SafeEventTile sometimes has the highlights prop undefined though I think SearchResultTile is always passing it correctly

Looks like plaintext messages (ones without formatted_body) don't get highlights

This pretty much has to be regression otherwise it'd have barely ever worked pre-replies, as those force a lot more messages to be formatted
