Reactions appear on mobile but not on web

[elias-pap]

Steps to reproduce

I sent a message in a thread and got 2 reactions. They appear on Element android app (running on a mobile phone) but not on Element web (running on a laptop). When I click View source on Element web the reactions seem to exist:

{
    "content": {
      "body": "<redacted-for-bug-report>",
      "m.relates_to": {
        "event_id": "$1672088044146141qwXFt:matrix.org",
        "is_falling_back": true,
        "m.in_reply_to": {
          "event_id": "$1672135484158278GVQRJ:matrix.org"
        },
        "rel_type": "m.thread"
      },
      "msgtype": "m.text"
    },
    "event_id": "$1672147780162587NqRjl:matrix.org",
    "origin_server_ts": 1672147780073,
    "room_id": "<redacted-for-bug-report>",
    "sender": "@eliaspap:matrix.org",
    "type": "m.room.message",
    "unsigned": {
      "age": 347964109,
      "m.relations": {
        "m.annotation": {
          "chunk": [
            {
              "type": "m.reaction",
              "key": "👎️",
              "count": 1
            },
            {
              "type": "m.reaction",
              "key": "😂",
              "count": 1
            }
          ]
        }
      }
    },
    "user_id": "@eliaspap:matrix.org",
    "age": 347962925
  }

On web:

Also I tried to add a thumbs down reaction on mobile (i.e. click the already existing thumbs down reaction) and this does appear on web, where I see only one thumbs down reaction and no other reactions. The source code in that case looks like this:

{
  "content": {
    "body": "<redacted-for-bug-report>",
    "m.relates_to": {
      "event_id": "$1672088044146141qwXFt:matrix.org",
      "is_falling_back": true,
      "m.in_reply_to": {
        "event_id": "$1672135484158278GVQRJ:matrix.org"
      },
      "rel_type": "m.thread"
    },
    "msgtype": "m.text"
  },
  "event_id": "$1672147780162587NqRjl:matrix.org",
  "origin_server_ts": 1672147780073,
  "room_id": "<redacted-for-bug-report>",
  "sender": "@eliaspap:matrix.org",
  "type": "m.room.message",
  "unsigned": {
    "age": 349844142,
    "m.relations": {
      "m.annotation": {
        "chunk": [
          {
            "type": "m.reaction",
            "key": "👎️",
            "count": 2
          },
          {
            "type": "m.reaction",
            "key": "😂",
            "count": 1
          }
        ]
      }
    }
  },
  "user_id": "@eliaspap:matrix.org",
  "age": 347962925
}

So it seems it can render my own reaction but it cannot render the reactions of others.

Outcome

What did you expect?

The same reactions should render on both clients.

What happened instead?

Element web renders two reactions less (it does not render a 👎️ and a 😂).
