If I do a podcasts search for something random for example, then click the link to share it, it gets copied with region and some 'sh' information as well. So when I open that link in a new tab, a large clear button appears that clears this extra search info. Even though podcast search doesn't have an option for searching with region. So it's not entirely obvious what the 'clear' button is doing in this case or why it shows up.
For example, here is a link I get when I try to share a podcast search:
https://kagi.com/podcasts?q=cats&r=no_region&sh=jln2GJ4oej1LAxUV_Y_jSw
If you click it, you'll see that there is a clear button where the filters are. But in the UI no filters are selected.
Either the podcast search it using region data but isn't showing it. Or it isn't but is erroneously including that information when generating the share link.
