As an editor I want to understand what the warning icon means in order to fix it/make it go away.
**Problem:**
Currently when seeing the “potential issues” icon I don’t know what the problem with my statement is. We should give you more context and explanation in a popper.
**Mockups:**
{F30389429}
Spec: All like the constraint violation popper. It should look and behave the same.
**BDD**
GIVEN The icon is visible
AND I click on it
THEN a popper opens up
AND there is an explanation text ("The value changed, but the reference remained the same.")
GIVEN The popper is open
AND I click anywhere outside the modal, on the x or press ESC
THEN the popper closes
**Acceptance criteria:**
[] popper pops up when clicking the potential issues icon
[] popper closes when clicking outside the popper or x or pressing ESC
[] a click on any other keys are not part of this story and will be left out
[] assume the text on the popper will be static
