QTextCursor::insertHtml() may break formatting

Consider the following example:

#include <QtGui>

int main(int argc, char *argv[]) {
QApplication app(argc, argv);

QTextEdit edit1;
QTextEdit edit2;

QStringList items;

items << "<font color=\"blue\"><pre>---- 13:24:58.118 ------------------\n"
"MESSAGE_ONE\n"
"(1) Trailing newlines before a closing PRE get stripped\n"
"------------------------------------\n"
"</pre></font>\n";

items << "<font color=\"green\"><pre>---- 13:24:58.118 ------------------\n"
"MESSAGE_TWO\n"
"The first line of this has run up against the last line of MESSAGE_ONE\n"
"------------------------------------\n"
"</pre></font>\n";

items << "<p> </p><p> </p><p> </p>";

items << "<font color=\"blue\"><pre>---- 13:24:58.118 ------------------\n"
"MESSAGE_ONE\n"
"(3) Additionally, the HR below this message \n"
"seems to be appearing in the wrong place\n"
"------------------------------------\n"
"</pre></font>\n";

items << "<p><hr/></p>";

items << "<font color=\"green\"><pre>---- 13:24:58.118 ------------------\n"
"MESSAGE_TWO\n"
"details\n"
"------------------------------------\n"
"</pre></font>\n";

QString html;
QTextCursor cursor = edit1.textCursor();

foreach(QString item, items)

{ cursor.insertHtml(item); html.append(item); }

cursor = edit2.textCursor();
cursor.insertHtml(html);

edit1.show();
edit2.show();

return app.exec();
}

The expected result is that both QTextEdits display the content in the same way. However, edit1 which uses QTextCursor::insertHtml() for each item in the string list, does not display the HTML correctly. The formatting is broken: The end of the first <pre> block and the the beginning of the second <pre> block appear on the same line, and the <hr> tag which should be rendered between the two <pre> blocks in a separate paragraph, is rendered between the two first lines of the last <pre> tag instead.
