Comment (by mordauk):

 We don't know what change exactly caused the issue, we just know what the
 behavior is.

 In earlier versions media frames persisted, now they don't. For example,
 Easy Digital Downloads has an integration with Amazon S3 (what angel8888
 mentioned above) that uses an iframe to pull in files from Amazon S3.
 Prior to a recent change, a site owner could open the media library from a
 post edit screen, navigate to the file they wished to use, insert it into
 the post (resulting in the media window being closed), then re-open the
 add media screen and the media library would be in the same state as it
 was after inserting the first file. Now, however, the media window resets
 to the default state each time it is opened instead of remembering the
 user's previous tab.

 The tabs we add are done using the standard method that is shown here
 https://codex.wordpress.org/Function_Reference/wp_iframe

 It seems the problem with losing the previous state only occurs with
 custom tabs. The default media tabs remember their state fine.
