Steps to reproduce: 1. Go to a blog post 2. Add a header 3. Hide the element on desktop and save 4. Click the button to translate the page When translating a page, `getScrollOptions` is not initialized, which throws an error when updating invisible DOM, as it could require the function to be loaded. This is because `_updateInvisibleDOM` needs this property to be set.
