If we use the builder to add our own <h1> heading template for the blog home page, instead of inputing a title into the blog element, it still outputs an empty <h1> tag causing two <h1> tags on the page (the empty one and the one we added).
This is not ideal for SEO.
If we want to use the builder for improved style control (mobile/desktop) and also maybe have a subtitle or paragraph below we should have the choice, and if so the empty <h1> tag should not be output on the page.
