Preview and the Rendered text should be the same size

1) Preview text should show what will be rendered; currently not matching for h tags

2) Request you revert to the "old" rendered styles for H tags as they were more impactful and useful. Current styles (esp h2 and h3) too closely match regular bold text to be useful. (And the extra giant spaces above the text is not in-line with how these headings are used. My 2 cents
