In question type Drag and drop onto image (ddimageortext), multilang filters don't work

Install a multilang filter plugin which doesn't relay on html tags, e.g. https://moodle.org/plugins/filter_multilang2 . This is since tags in Drag and drop onto image questions, with some exceptions, HTML tags are not very welcome. Enable that filter plugin for content and headings (in fact, without headings the fix does not work). Aside english install at least another language, e.g. Russian In a course, go to question bank Create a new {{ Drag and drop onto image}} question, name it MDL-61286 test question Let the question text be: {mlang en}Guess the color{mlang}{mlang ru}Угадайте цвет{mlang} Add the attached redblue.png background image Let the draggable item 1 of type draggable text be: {mlang en}red{mlang}{mlang ru}красный{mlang} Let the draggable item 2 of type draggable text be: {mlang en}blue{mlang}{mlang ru}синий{mlang} Let drop zone have item 1 and left 50 and top 100 Let drop zone have item 2 and left 50 and top 300 Save changes and continue editing and then preview Cross check in english you see the english question text and labels.
