I finally found cause to use one that allows you to preview the text
before sending. Indeed the newlines, in whatever form I enter them,
are copied straight into the HTML, inside a <div>. Manually added
<br>s and <p>s were stripped out, which is really a good thing.

So they simply haven't cared to use a function which replaces
newlines with <br> or <p>. Just lazyness or a lack of testing I
guess, though it seems strange given that these are often very
major websites.
