Images no longer reserve their space in the timeline correctly

[turt2live]

Steps to reproduce

1. Receive an image message
2. Note that the tile is small while loading
3. Timeline jumps when image loads

Outcome

What did you expect?

The blurhash and skeleton loading animation from past releases, and for the space to be reserved in the timeline.

What happened instead?

^during load

^after load

The event does have dimension information in it:

{
  "type": "m.room.message",
  "content": {
    "body": "image.png",
    "info": {
      "size": 98660,
      "mimetype": "image/png",
      "w": 1085,
      "h": 764,
      "xyz.amorgan.blurhash": "REDACTED"
    },
    "msgtype": "m.image",
    "file": {
      "v": "v2",
      "key": { REDACTED },
      "iv": "REDACTED",
      "hashes": {
        "sha256": "REDACTED"
      },
      "url": "mxc://REDACTED"
    }
  }
}

I believe this started happening after the security release.
