Activity completion ticks appear before close date and disregarding quiz review options

Follow these steps to reproduce:

Quiz settings:

• Timing: Set a close date
• Grade: Set a passing grade, multiple attempts, highest grade
• Review settings: Check all under "After quiz is closed". Uncheck all others.
• Activity completion: check "Require Grade", "Require passing grade" and "Or all available attempts completed"

1. Login as student
2. Perform quiz and don't pass
3. No tick appears
4. Perform quiz and pass
5. Blue tick appears even though quiz is not closed yet 

I would prefer that students don't see any tick (neither blue, nor green) until the quiz is closed.

Currently, no tick appears until the student passes a quiz.
But as soon as a student passes one of multipe attempts, even though the quiz is not yet closed, a blue tick appears.

Students already found out about this behaviour and can share the correct answers immediately.

Besides that, the tick should be green and not blue if a passing grade is set and the corresponding activity completion setting.
When I select "Marks" under "Later, while the quiz is still open"  in the "Review options" and unlock the completion options, the ticks turn green.
