HTML output of qdoc's \br command is incorrect

The HTML output of qdoc's \br command is incorrect, probably since the \br macro was promoted to a qdoc command (QTBUG-26435). The expected HTML output would be:

<br />

The actual HTML output is:

</p>
<br />
<p>

For an example of the outcome, see the gap between the copyright statements at http://doc-snapshot.qt-project.org/qt5-stable/licenses.html#parts-of-the-codecs-implemented-by-qt.

Given the facts that \br is still undocumented as a qdoc command and that even qtdoc/doc/global/macros.qdocconf still defines macro.br.HTML = "<br />", the result is really confusing.

I guess the issue is triggererd by leavePara() in qtbase/src/tools/qdoc/doc.cpp DocParser::parse() at:

                case CMD_BR:
                    leavePara();
                    append(Atom::BR);
                    break;

(Maybe the leavePara() was motivated by DITAXML output?)
