Using datasette==0.63 table filters do not respect the base_url setting as described here
To reproduce, go to:
https://datasette-apache-proxy-demo.datasette.io/prefix/fixtures/binary_data
Then use the table filter buttons.
The /prefix/ is dropped, resulting in URL not found:
https://datasette-apache-proxy-demo.datasette.io/fixtures/binary_data?_sort=rowid&rowid__exact=1
