Widgets should be able to specify that they can handle certain media types. This allows advanced drag n' drop handling in the editor, such as automatically creating a ww-figure widget out of an image dragged into the editor.
Specification by developers
A static property mediaTypes on the widget's constructor is used to specify which media types the widget can handle. This is an array of valid MIME type strings.
// Imports are omitted
@customElement("my-widget")
class MyWidget extends LitElementWw {
static mediaTypes = ["image/png", "image/svg"]
}
Editing by teachers
When something is dropped or pasted into the editor, the media type should be checked. If the media type has no registered handler, a warning should be shown. If the media type has exactly one registered handler, a new handler element is created at the drop location and a drop or paste event is triggered synthetically on the newly created element. If the media type has two or more registered handlers, a dialog should be shown where the user can pick a handler.
