* insertParagraph command in plaintext-only is available only with document.execCommand.
* It should work as same as contenteditable=true, therefore, this test checks only
* basic behavior. Various edge cases should be tested in run/insertparagraph.html.
*
* Currently, <br> is used for padding line break in empty paragraph. This won't appear
* in `.textContent` of the editing host, but the paragraph itself does not appear in
* the value too. Therefore, web apps anyway need to use `.innerHTML` to get the result.
* So, using <br> should not be a problem for web apps.
