/**
* The decoupled editor implementation. It provides an inline editable and a toolbar. However, unlike other editors,
* it does not render these components anywhere in the DOM unless configured.
*
* This type of an editor is dedicated to integrations which require a customized UI with an open
* structure, allowing developers to specify the exact location of the interface.
*
* See the document editor {@glink examples/builds/document-editor demo} to learn about possible use cases
* for the decoupled editor.
*
* In order to create a decoupled editor instance, use the static
* {@link module:editor-decoupled/decouplededitor~DecoupledEditor.create `DecoupledEditor.create()`} method.
*
* Note that you will need to attach the editor toolbar and menu bar to your web page manually, in a desired place,
* after the editor is initialized.

/**
* Creates a new decoupled editor instance.
*
* **Note:** remember that `DecoupledEditor` does not append the toolbar element to your web page, so you have to do it manually
* after the editor has been initialized.
*
* There are two ways how the editor can be initialized.
*
* # Using an existing DOM element (and loading data from it)
*
* You can initialize the editor using an existing DOM element:
*
* ```ts
* DecoupledEditor
* .create( document.querySelector( '#editor' ) )
* .then( editor => {
* console.log( 'Editor was initialized', editor );
*
* // Append the toolbar to the <body> element.
* document.body.appendChild( editor.ui.view.toolbar.element );
* } )
* .catch( err => {
* console.error( err.stack );
* } );
* ```
*
* The element's content will be used as the editor data and the element will become the editable element.
*
* # Creating a detached editor
*
* Alternatively, you can initialize the editor by passing the initial data directly as a string.
* In this case, you will have to manually append both the toolbar element and the editable element to your web page.
*
* ```ts
* DecoupledEditor
* .create( '<p>Hello world!</p>' )
* .then( editor => {
* console.log( 'Editor was initialized', editor );
*
* // Append the toolbar to the <body> element.
* document.body.appendChild( editor.ui.view.toolbar.element );
*
* // Initial data was provided so the editor UI element needs to be added manually to the DOM.
* document.body.appendChild( editor.ui.getEditableElement() );
* } )
* .catch( err => {
* console.error( err.stack );
* } );
* ```
*
* This lets you dynamically append the editor to your web page whenever it is convenient for you. You may use this method if your
* web page content is generated on the client side and the DOM structure is not ready at the moment when you initialize the editor.
*
* # Using an existing DOM element (and data provided in `config.initialData`)
*
* You can also mix these two ways by providing a DOM element to be used and passing the initial data through the configuration:
*
* ```ts
* DecoupledEditor
* .create( document.querySelector( '#editor' ), {
* initialData: '<h2>Initial data</h2><p>Foo bar.</p>'
* } )
* .then( editor => {
* console.log( 'Editor was initialized', editor );
*
* // Append the toolbar to the <body> element.
* document.body.appendChild( editor.ui.view.toolbar.element );
* } )
* .catch( err => {
* console.error( err.stack );
* } );
* ```
*
* This method can be used to initialize the editor on an existing element with the specified content in case if your integration
* makes it difficult to set the content of the source element.
*
* Note that an error will be thrown if you pass the initial data both as the first parameter and also in the configuration.
*
* # Configuring the editor
*
* See the {@link module:core/editor/editorconfig~EditorConfig editor configuration documentation} to learn more about
* customizing plugins, toolbar and more.
*
* @param sourceElementOrData The DOM element that will be the source for the created editor
* or the editor's initial data.
*
* If a DOM element is passed, its content will be automatically loaded to the editor upon initialization.
* The editor data will be set back to the original element once the editor is destroyed only if the
* {@link module:core/editor/editorconfig~EditorConfig#updateSourceElementOnDestroy updateSourceElementOnDestroy}
* option is set to `true`.
*
* If the initial data is passed, a detached editor will be created. In this case you need to insert it into the DOM manually.
* It is available via
* {@link module:editor-decoupled/decouplededitorui~DecoupledEditorUI#getEditableElement `editor.ui.getEditableElement()`}.
*
* @param config The editor configuration.
* @returns A promise resolved once the editor is ready. The promise resolves with the created editor instance.
