As an editor I want to be able to confirm an existing reference if my edit doesn't invalidate it in order to remove the warning.
**Problem:**
When fixing a typo in a value for example that does not invalidate the reference then I can only make the warning go away by reloading the page (This will be the situation after completion of T234790).

**BDD**
GIVEN an edit that changes the value but not the reference
AND the warning icon is visible
WHEN clicking on the warning icon the explanation is shown
AND I click the button "Remove warning" button confirm that reference still matches the value
THEN the popper closes
AND the warning icon goes away
**Acceptance criteria:**
[ ] When confirming the reference is fine the warning icon goes away
