Hovering over tag should make it clear that clicking will remove it

Usually when you see a tag on an interface, clicking it brings you to the search result page of that tag. But on Canny, clicking it removes the tag. A simple strikethrough or X upon hover would make it clear to the user and prevent you from accidentally removing tags.

I actually would prefer that you put a little "X" on tags to delete them so that we could copy the value and paste it somewhere else.
