Sticker label position with "Default" "Image size in the timeline"

### Steps to reproduce

This happens for one certain sticker that exceeds the "default" image size in the timeline.

1. Send a custom sticker using https://github.com/maunium/stickerpicker
```json
"content": {
"body": "Possibly",
"info": {
"h": 306,
"mimetype": "image/jpeg",
"size": 38952,
"thumbnail_info": {
"h": 306,
"mimetype": "image/jpeg",
"size": 38952,
"w": 300
},
"thumbnail_url": "redacted",
"w": 300
},
"url": "redacted"
}
```

Here is the mediainfo of the image in question:
```
Image
Format : JPEG
Width : 300 pixels
Height : 306 pixels
Color space : YUV
Chroma subsampling : 4:4:4
Bit depth : 8 bits
Compression mode : Lossy
Stream size : 38.0 KiB (100%)
ColorSpace_ICC : RGB
```

In particular, the image is displayed smaller (narrower) than another sticker that has a width of 265 px. The "default" setting of appearance -> "image size in the timeline" scales it down.

Inspecting both stickers with chrome devtools reveals an element gets inserted on hover. It has a `style=left: 300px` set for the broken sticker, and 265 px for the working sticker, apparently matching the `w` field from the event. It appears that this does not get scaled down to match the scaling of the image itself.

### Outcome

#### What did you expect?
usually, the label appears right next to the sticker.

this is with "large" "image size in the timeline" setting:
