WordPress 4.5.2, local installtion on Xampp 5.6.21
If I use the search (Navigation -> search) the search keys work. But I can't reset the search, not with empty input field and enter. Only with a refresh of the browser.
If I use search and filter and I had searched a string with the search funtionallity, I can't click on any of the filters. I think, that is a bug.
