Multiple drop providers can be registered for a language. When dropping content into an editor, all
registered providers for the editor's language will be invoked based on the mimetypes they handle
as specified by their DocumentDropEditProviderMetadata.
Each provider can return one or more DocumentDropEdits. The edits are sorted
using the DocumentDropEdit.yieldTo property. By default the first edit will be applied. If there
are any additional edits, these will be shown to the user as selectable drop options in the drop widget.
