Well, Riot-web renders it badly too. :/ yeah ... appears 2 times on the riot-web screenshot.

The issue comes from a malformed reply (there are 2 <mx-reply> blocks in event.content:

This event was created by Riot-iOS which failed to create a valid reply from https://matrix.to/#/!QtykxKocfZaZOUrTwp:matrix.org/$1540434413178IqzmN:raim.ist?via=matrix.org&via=half-shot.uk&via=disroot.org&via=t2bot.io.

Because the reply in it contains an unexpected newline (\n).
