Using that global variable was a bad idea. Stick to redux as the source of truth.
The flag is not listed for rehydration, so it will always start off as `undefined`, which is what we need anyways.
`undefined` indicates we haven't tested for ad-blockers, so we'll run the fetch and update the store with a true|false value.
It would be nice if the individual components can handle the remounting of the ad-script, but there is currently a need to synchronize the cleanup of the `window.OBR` object.
The quickest solution for now is to add a key at the parent side to synchronize the mount-unmounting. Not ideal -- revisit later.
- This increases the amount of ads, filling up the entire width. No more need to restrict with `max-width` ourself.
- Changed the ad-driver to top-right since the "Powered by Outbrain" text is now locked in bottom-right. Also made the container having a minimum height, as the method to "display the driver after ads are loaded" is not future proof -- it depends on the IDs being used by the ad. Reserving some space seems to be easiest, and it also reduces shifts as well.
## Behavior in homepage
- Mobile: show after every other category
- Desktop: show after first category, then every 2 categories.
## Known issue:
- "FYP" is not part of the categories array at the moment, so it does mess up the behavior.
## Notes
I think this is also called "in-content" by adnim (not 100% sure of the terminology).
