Repeated unnecessary API calls when changing theme filter

[dsas]

When toggling between the different filters free, premium, paid, and all in the theme showcase. We're triggering a network call to https://public-api.wordpress.com/wp/v2/sites/221022448/themes?status=active&_envelope=1 . The active theme is still the same so I'm not sure if we really need to perform that call for the purpose of filtering themes. On the other hand we aren't performing a call to retrieve a list of filtered themes (which makes sense).

Thanks for creating this @dsas I'll add some screenshots I had in case they're helpful.
