element-web: "Can't load this message (m.room.message)" on reply in thread

Steps to reproduce

I replied to a message in the main chat room, and chose to reply in thread, from Element Android.

In Element Web and Element Desktop, in place of my reply I see this:

Can’t load this message (m.room.message)

‘View source’ shows the message text correctly.

Outcome

What did you expect?

I expected to see my threaded reply correctly in the web and desktop clients.

What happened instead?

I see the error message: Can't load this message (m.room.message)

Underlying JavaScript error:
