On a 8.7.7 site I'm building, I'm using core media's video bundles, pointing to YouTube.
If I inspect the filesystem for the actual thumbnails downloaded by YouTube, I see stuff like this:

However, {media_field_data} has a totally different idea:
mysql> SELECT mid, thumbnail__width, thumbnail__height FROM media_field_data WHERE bundle = 'video' LIMIT 5;
+-----+------------------+-------------------+
| mid | thumbnail__width | thumbnail__height |
+-----+------------------+-------------------+
| 1 | 180 | 180 |
| 5 | 180 | 180 |
| 15 | 180 | 180 |
| 16 | 180 | 180 |
| 17 | 180 | 180 |
+-----+------------------+-------------------+

Thanks to image_preprocess_image_style(), this results in thumbnail markup like so:
<img src=".../sites/default/files/styles/320x180_small/public/video_thumbnails/S3sdd1i9pbQ.jpg?itok=L8Ug7t3z" width="180" height="180" alt="" typeof="foaf:Image" class="image-style-_20x180-small">
Those width and height attributes are bogus, since the metadata in the DB thinks those are the dimensions of the thumbnail. This results in unnecessarily small thumbnails that don't truly respect the image style as I defined it.
Record accurate dimensions for the thumbnail files in the media entity metadata stored in the DB.
Media thumbnails will know their accurate size/aspect ratio, hopefully resulting in better looking UI in places where media thumbnails are being displayed.
Hopefully none.
None.

I use an online service to download youtube video thumbnails with correct dimensions, all these dimensions follow youtube's pre-defined algorithm. The dimension of youtube HD image is 1280X720 Pixels. it may be helpful for someone.
