Complete DomConverter.blockElements array

📝 Provide a description of the improvement

DomConverter.blockElements doesn't include every possible block element. We should extend it to cover additional blocks like pre, section, article etc, so basically, every HTML tag considered a block/flow element. The change is required for full HTML support to correctly handle trailing spaces.

this.blockElements = [ 'p', 'div', 'h1', 'h2', 'h3', 'h4', 'h5', 'h6', 'li', 'dd', 'dt', 'figcaption', 'td', 'th' ];

Also, we could cover #3920
