Disable autorefreshing of page content at /library/artists when filter form is focused

Part of #1106 (closed) (read this issue for access to the full audit and recommendations).

Audit section (Section 3.2.1):

When one of the filter options receives the focus on page https://open.audio/library/artists the page immediately refreshes. A page shouldn’t initiate a change of context when an element receives the focus. See for instance the options ‘Ordering’ and ‘Order direction’ on page https://open.audio/library/artists.
