Selected category in showcase incorrect after navigation

[fen89]

On the showcase page if you change the category and navigate back and forth the displayed showcases are incorrect.

Steps to reproduce:

• Open https://nuxt.com/showcase
• Change category to Tech
• Querystring will change to https://nuxt.com/showcase?category=Tech

• Click on one showcased website and hit the back button to go back to nuxt.com
• The querystring still contains (correctly ) ?category=Tech - the showcase cards contain the correct tech titles and descriptions, but the images and the urls are not aware anymore that the Tech category is still active in the querystring. Navigation is back to Featured but the content is still not quite correctly displayed; it is completely mixed up now:
