Questionnaire (plugin)

Situation is similar to the one in my previous post...

1. A questionnaire is set to Save/Resume answers YES.
2. Students A, B, C answer the questionnaire completely and submit it.
3. Students D and E start to answer the questions and Save their answers without submitting.
4. Teacher decides to View all Responses. The "Total responses to question" line shows a discrepancy between the number of respondents to the question and the number of responses, as per attached screenshot.

Solution suggested is to add one line to \questionnaire\classes\responsetype\responsetype.php in public function get_results_tags():

$respondents = min($respondents, $participants);
