Description

• When reviewing a Cloze question a user can hover over a submitted answer to reveal a pop-up showing feedback about correctness, marks, etc.
• When using a question behavior such as "Immediate feedback," "Adaptive," or "Interactive with multiple tries" the question layout includes a "Check" button that is visible but disabled on review.
• The feedback pop-up displays behind the check button when the two overlap

I have observed the problem in Firefox, Chrome and Safari and in 2.8dev, 2.7 and 2.6

Steps to replicate

1. Create a quiz (or use the attached Quiz backup and skip the next two steps)
2. Use "Immediate feedback" as the question behavior and check all feedback options available "During the attempt"
3. Add a simple "Embedded" (Cloze) question such as: {:SA:=test}
4. Take the test, entering anything into the answer field
5. Click the "Check" button
6. When you hover over the answer field, the feedback should (but does not currently) display in front of the check button
7. Finish and review the attempt
8. Test the hover behavior again
