If I paste some text into the Typography Component, the line breaks in the text pasted are ignored and the text just runs on when previewed in a browser.
However, if text is typed into the Typography Component any returns are respected and retained.
The video shows in the first Typography component text pasted into the Typography component, from a plain text file file from BBEdit. Each paragraph is separated by two returns. The second Typography component shows the default text, with a couple of returns entered. Then the page is previewed in Safiri. There is the same result in FireFox.
