Comment 2 for bug 2065326

Nice catch, Vince! We had previously changed the keyword search input type from "text" to "search", which in some browsers adds the affordance you noticed. I've made this change for all the other tabs' search query inputs in this branch:

To test, use any browser other than Firefox to search the catalog, using any tab other than Keyword Search. Enter any text, and the "X" should appear.
