Youtube Playlists API pageInfo.totalResults and items are inconsistent

Question

The Youtube Playlists API playlistResponse.pageInfo.totalResults and playlistResponse.items are inconsistent.

pageInfo.totalResults includes the “Liked videos” playlist, however, items does not include this playlist.

This issue is easier to observe if the number of playlists in the account is less than maxResults.

Call the list method with the following request parameters:

• maxResults: 50
• mine: true

Actual result: totalResults includes the "Liked Videos" playlist. For example, if the user has 7 playlists, totalResults is 8 as it includes “Liked videos”

Expected result: Either totalResults does not include the “Liked videos” playlist, or items does.

For example, I have 7 playlists, 8 including "Liked Videos". Here totalResults includes the "Liked Vidoes" playlist, whereas items does not.
