The Preview-as-visitor functionality does not apply traits correctly. Magnolia does not serve the variants that it should.

To reproduce on demo:

1. Create two variants for /sportstation. The order of variants is important.
   • London: Country=United Kingdom AND Cookie WeatherLocality=London
   • UK: Country=United Kingdom
2. Preview the page as visitor. Set Country=United Kingdom.
   • Expected: London variant is served. Both variants have equal weight (1 matching trait) so we serve whichever variant comes first (London).
   • Actual: UK variant is served although it is second in the variant order.
3. Move the UK variant to first place, above London.
4. Preview as visitor. Set Country=United Kingdom and WeatherLocality=London
   • Expected: London variant is served. London now has more weight (2 matching traits) so we serve it first regardless of variant order.
   • Actual: UK variant is served.
