     * The default value is:
     *
     * ```ts
     * const lineHeightConfig = {
     *   options: ['default', 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 2, 2.5]
     * };
     * ```
     *
     * As an alternative, the line-height might be defined using numerical values (either as a `Number` or as a `String`):
     *
     * ```ts
     * const lineHeightConfig = {
     *   options: ['default', '10px', 2, '150%', '8em', { title: 'Custom Title', model: '48px' }]
     * };
     * ```
     *
     * Also, you can define a label in the dropdown for numerical values:
     *
     * ```ts
     * const lineHeightConfig = {
     *   options: [
     *     'default',
     *     {
     *       title: 'Normal',
     *       model: '1',
     *     },
     *     {
     *        title: 'Custom Title',
     *        model: '48px'
     *     },
     *   ]
     * };
     * ```
     *
     * Line height can be applied using the command API. To do that, use the `'lineHeight'` command and pass the desired line-height as a `value`.
     * For example, the following code will apply the `lineHeight` attribute with the **tiny** value to the current selection:
     *
     * ```ts
     * editor.execute('lineHeight', { value: 1.5 });
     * ```
     *
     * Executing the `lineHeight` command without value will remove the `lineHeight` attribute from the current selection.

     * By default the plugin removes any `line-height` value that does not match the plugin's configuration.
     * It means that if you paste content with line heights that the editor does not understand, the `line-height` attribute
     * will be removed and the content will be displayed with the default height.
     *
     * You can preserve pasted line height values by switching the `supportAllValues` option to `true`:
     *
     * ```ts
     * const lineHeightConfig = {
     *   options: ['default', 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 2, 2.5],
     *   supportAllValues: true
     * };
     * ```
     *
     * With this configuration line heights not specified in the editor configuration will not be removed when pasting the content.
