Description: 

AttachedAssets has a new createFromAttachments() factory.

Instead of wrapping an existing array of attachments in a temporary render array or initializing AttachedAssets from ground up, the attachments array may now be passed directly to AttachedAssets::createFromAttachments() to initialize an AttachedAssets collection with libraries and JavaScript settings:

$assets = AttachedAssets::createFromAttachments($attachments)
