How can I add tag filtering to my product collection page without resetting other filters?

Hello!

I’m trying to add tag filtering to my products collection page. I used the code provided here https://shopify.dev/themes/navigation-search/filtering/tag-filtering#implementing-tag-filtering, which works for filtering (by adding the tags to filter to the url). But when i click on one of the tags, the other filters (availability, price etc., which are set in the facets.liquid file) reset and the filter banner disappears from the page.

I’m using the theme Taste. Please help!
