Created an test with File Upload question types.
Took the test as a student, uploaded a file then click on remove.
Frame resize (i.e. height is 1/3 of what it was), confirmation message appears. Remove file.
Are taken back to the question in test but frame does not resize back to what it was, remain small until you finish the test.
Once you've taken to the front page of test and quizzes the frame is big again.
