1. Click "Init editor". 2. Expected: * Inline editor should be created. * The element used as editable should remain visible. * It should preserve `.custom-class` and `custom-attr="foo"`. * There should be a floating toolbar with "Bold", "Italic", "Undo", "Redo", "Link" and "Unlink" buttons. 3. Scroll the webpage. 4. Expected: * The toolbar should float around but always stick to editable. * The toolbar should stick to the bottom of the editable if there's not enough space above. 5. Click "Destroy editor". 6. Expected: * Editor should be destroyed. * The element used as editable should remain visible. * It should preserve `.custom-class` and `custom-attr="foo"`. * The element should contain its data (updated). * The 'ck-body region' should be removed. ## Notes: * You can play with: * `editable.isReadOnly`, * Changes to `editor.focusTracker.isFocused` should be logged to the console. * Features should work.
