Playlist widget losts pagination on non-node entities

The field "Brightcove" with "Playlist (create/browse)" losts pagination on edit forms in case if field attached to paragraph entity instead of node entity itself.

Steps to reproduce

1. Install paragraphs
2. Install and configure Brightcove
3. On "/admin/config/media/brightcove" page set "Playlists pager max items" to "5".
4. Create 6 or more Brightcove playlists "/admin/config/media/brightcove/playlist" if there are less than 6 of existing playlist in the Brightcove client being used.
5. Create a new paragraph bundle with "Brightcove" field and "Playlist (create/browse)" widget
6. Create a new field in any content type of "Paraghraph" type with "Embed" widget.
7. Create a new node, add paragraph with playlist field inside. Select playlist from second page or higher. Save node.
8. Open node edit page, observe the issue: Playlist pagination is on the first page, "No playlist selected" option is chosen.

Current behavior

On node edit page when brightcove playlist field is attached to paragraph entity instead of node, previously selected playlist ID is lost in case if page number > 1.

Expected behavior

On node edit page when brightcove playlist field is attached to paragraph entity instead of node, previously selected playlist ID should be kept even if page number > 1.
