Works better, but it has its share of weirdness. Just by clicking around on a "lorem ipsum" text it seems to work okay in Firefox (beta) and Camino (i.e. two Gecko versions), not at all in Chrome dev (clicking on italic/bold/h1 won't change anything) and if I select a line in Safari to make it a headline, it also applies the transformation to the following paragraph. If I then click "h1" again, everything is back to normal. A third click then works as intended, i.e. only the selected line is turned into a headline. From then on, this line works normal, but the whole game repeats itself if I do it with another line.
