#2981105: Media Library should not modify the media view
#3081587: Multilingual content is shown double in the media library view
#2962110: Add the Media Library module to Drupal core

In Drupal 8.6 and 8.7, Media Library would take over the /admin/content/media path when installed, changing the original administrative table view's path to /admin/content/media-table and replacing the content at /admin/content/media with the Media Library grid view. This could lead to data loss if the site had customized the default table view before installing Media Library.

In 8.8, the /admin/content/media path has been restored to show the table view, as it does without Media Library installed
