T411604 introduces icons to the display of statements. These icons should be clickable, and when clicked should open up a popover that explains the significance of the icon.
The contents of the popover should be defined by the WikibaseQualityConstraints extension - there will need to be a mechanism to associate popover design / HTML content with the icon when icons are added to the pinia store for a snak.
Acceptance Criteria
- Popovers can be associated with icons and when the icons appear next to snaks, clicking on the icons shows the popover (which can then be dismissed again)
Notes
- Depending on the progress with T411606 T411604 and T411602, it may already be possible to test this end-to-end. If not, it suffices for the purposes of this ticket to introduce the popover mechanism and cover it with unit tests. The final implementation will come in T411609
- All of the content should be generated (and formatted) by QualityConstraints
