== Story
As a navpopups user, I want the ability to try out the hovercards feature, to see which one I like better
== Solution
Navpops users won't be able to enable Page Previews unless they disable Navigation Popups gadgets from gadgets tab. We cannot disable it for users, the user has to do it manually. we can link to the gadgets tab though.
Here's how it will look

The blue link that says "disable navigation popups" will link to https://en.wikipedia.org/wiki/Special:Preferences#mw-prefsection-gadgets or just the hashtag "mw-prefsection-gadgets"
==Acceptance Criteria
1. If user had navigational popups enabled
- Disable "previews on" option
- Display message: "For page previews to work, please disable navigational popups from [the gadgets tab]"
- Selecting link will navigate to gadgets
- We log this as part of the Popups instrumentation
2. If we DO NOT KNOW whether the user has navigational popups enabled:
- Enable both options
- Display message: "Certain gadgets and other customization may affect the performance of this feature. If you notice issues with page previews, please go through your gadgets list and other customization"
== Plan
* Per {T154573}, we forward `conflictsWithNavPopupsGadget` to the client in the `onMakeGlobalVariables` script and include its value in Popups events.
