在一个 angular 项目中，从 angular 15 升级到 angular 17 后遇到的问题，下面的代码中设置 renderSideBySide 为 true 对 monaco editor 不起作用，总是在一个编辑器中显示 diff，monaco editor 是通过 ngx-monaco-editor-v2 的 ngx-monaco-diff-editor 加载的

onDiffEditorInitialized(editor: monaco.editor.IStandaloneDiffEditor) {
    this._preferenceChangeSubscription?.unsubscribe();
    this._preferenceChangeSubscription = this._preferenceManager.preferenceChange
        .pipe(
            this._rxHelper.autoUnsubscribe,
            map(
                ({ sideBySide }): Partial<monaco.editor.IDiffEditorOptions> => ({
                    renderSideBySide: sideBySide,
                })
            )
        )
        .subscribe(opt => editor.updateOptions(opt));

    this._diffEditor = editor;
    this._zone.run(() => (this.hasDiffEditorInitialized = true));
}
