If no maps when filtering, no way to go back

Sorry for the title, this is hard to describe, so here's steps to reproduce:

1. Load Mati's page - https://inkarnate.com/p/34K9WG

   It takes a long time to load because he makes so many freakin' maps!

2. Change the map type filter (Where it says 'All' currently) to "Style: Fantasy Regional Basic".

3. BUG There's no maps using this filter, the page is empty, and there is also no way to now change the map type filter (it's no longer there), so the only way to get back to Mati's maps is to start again at step 1 and deal with the long load time again.

Solution: I'd like to see the filter drop downs remain, even on an empty page, so I can continue looking at maps without having to reload or start over.
