--------------------------+-----------------------------
 It seems like WordPress does not update the 'filesize' metadata after an
 image is modified through the media library. The details panel in the
 media library displays the original file size instead of the 'new' file
 size.

 === Environment

 - WordPress: 6.3.3-alpha-56924
 - PHP: 8.2.10
 - Server: Apache
 - Database: mysqli (Server: 5.7.31 / Client: mysqlnd 8.2.10)
 - Browser: Chrome 118.0.0.0 (Windows 10/11)
 - MU-Plugins: None activated
 - Plugins:
     - WordPress Beta Tester 3.5.4

 The following optional modules are not currently installed on our server:

 - exif
 - fileinfo
 - imagick

 === Steps to Reproduce

 1. Upload a new image in the media library
 2. Note the file size (ie. 22 KB)
 3. Resize the image by clicking on 'Edit Image', then 'Scale Image' (in my
 test case, I resized the image from 1920x1080 to 200x113)
 4. Click 'Update'
 5. The 'Dimensions' field is correctly updated, but 'File size' remains
 the same (22 KB)

 === Expected Results

 The 'File size' should display the new file size (ie. 3.3 KB)

 === Actual Results

 The 'File size' field displays the size of the original image, before it
 was resized.

 Here is the value of the '_wp_attachment_metadata' field in the database
 after the media is resized:

 {{{

 }}}

 The "filesize" metadata has the value '22990' instead of '3033'.
