Edit pencil showing up on event edited by other user

[krille-chan]

Description

When a user sends an m.text that relates to (with type m.replace) an event sent by a different user, the original message gets the "edited" pencil as if it was edited.

To Reproduce

Have 2 users. User 1 sends a regular message. User 2 sends an m.text type message with {"m.relates_to": {"rel_type": "m.replace", "event_id": "(event ID of message sent by user 1)"}}

Example:

• Event 1:

{
  "type": "m.room.message",
  "sender": "@testaccount:example.org",
  "content": {
    "org.matrix.msc1767.text": "!poll \"test\" \"1\" \"2\"",
    "body": "!poll \"test\" \"1\" \"2\"",
    "msgtype": "m.text"
  },
  "origin_server_ts": 1649748911891,
  "unsigned": {
    "age": 139
  },
  "event_id": "$2NLEbKxQ-DyDn58kAM-HhqSydV02qStn66zgufsoAtk",
  "room_id": "[redacted]"
}

• Event 2:

{
  "type": "m.room.message",
  "sender": "@testaccount2:example.org",
  "content": {
    "msgtype": "m.text",
    "body": "* Poll:\ntest\n🇦: 1\n🇧: 2\n",
    "m.new_content": {
      "msgtype": "m.text",
      "body": "Poll:\ntest\n🇦: 1\n🇧: 2\n"
    },
    "m.relates_to": {
      "rel_type": "m.replace",
      "event_id": "$2NLEbKxQ-DyDn58kAM-HhqSydV02qStn66zgufsoAtk"
    }
  },
  "origin_server_ts": 1649748912124,
  "unsigned": {
    "age": 116
  },
  "event_id": "$lnzIpJXg6QHWa18ffe51NBsGPSVsXbaKff1KvSyiRXU",
  "room_id": "[redacted]"
}

• Result (as seen from testaccount2, it appears the same on testaccount):
