Multianswer question wrongly displays correctness div flush with Submit button

This problem only occurs with MULTIANSWER (aka Cloze) questions. It only occurs in Moodle versions 1.9 and 2.0.

In a Quiz set as Adaptive mode, when the Submit button to a Multianswer question is clicked, the correctness div is displayed Flush with the Submit button rather than on another 'line" as expected.

I have found two ways to fix this bug.

Solution #1 - hack the code in question/type/multianswer/questiontype.php (line numbering valid for 1.9)
line 210 change to:
// For this question type, we better print the image on top:
if ($image = get_question_image($question))

{ echo('<img class="qimage" src="' . $image . '" alt="" /><br />'); }

echo('<div class="ablock clearfix">'); // ADD THIS LINE HERE
$qtextremaining = format_text($question->questiontext,
$question->questiontextformat, $formatoptions, $cmoptions->course);
and line 340 change to:
// Print the final piece of question text:
echo $qtextremaining;
$this->print_question_submit_buttons($question, $state, $cmoptions, $options);
echo('</div>'); // ADD THIS LINE HERE

Solution #2: change CSS declaration in theme/standard/styles_layout.css
line 2536 replace :
.que .submit {
position: relative;
clear: both;
float: left;
}
/* MSIE Hack */

• html .que .submit {
  float: none;
  }

with

.que .submit {
position: relative;
clear: both;
}
i.e. the float declaration is NOT needed, and is causing the problem... Why was it put there in the first place?

TESTED with MSIE 7 and FireFox 2.0
