Describe the bug
A portrait clip recorded on an iPhone will be stored as landscape but with rotation information embedded.
The clip plays fine and everything work except for the scene cards that do not get the css class portrait.

Relevant ffprobe output:

Stream #0:0[0x1](und): Video: hevc (Main) (hvc1 / 0x31637668), yuv420p(tv, bt709), 3840x2160
...
Metadata:
  creation_time   : xxxxx
  handler_name    : Core Media Video
  vendor_id       : [0][0][0][0]
  encoder         : HEVC
Side data:
  displaymatrix: rotation of -90.00 degrees

To Reproduce
Steps to reproduce the behavior:

1. Record a clip vertically with an iPhone
2. Scan it
3. The thumbnail and the video preview in the scene card will only show the top part of the image.
4. The scrubber in the scene card will show the whole image as expected

Somewhat related to this:

1. For portrait mode clips the scrubber in the player page only shows the upper side of the image.
2. For portrait mode clips that have landscape thumbnails (think a short clip from yt downloaded with yt-dlp) the video preview is taller than the thumbnail. To fix it I had to disable making the portrait mode taller by adding the custom css (only for zoom-1, since that is what I use):

.zoom-1 .portrait {
  height: 180px;
}

Expected behavior
The way the scrubber looks on the scene card is the way that the portrait thumbnail and video preview should look like on the scene card.
