Issue: search input box appears an extra time every time you enter and exit the World search screen.
Reproduction Steps:
  1. Open up worlds tab and click on the 'Search Worlds' button
  2. Type a search into the search bar and submit
  3. Observe a second search bar appear after submitting the first one.
  4. Either exit out of the second search bar or submit a second time.
  5. Hit the back arrow to go back to the main Worlds screen.
  6. Observe a new search bar appear despite being on the main worlds screen now.
  7. Submit the search to go back to the search results screen or exit it to remain on the main worlds menu.
Expected Behavior:
On live you only get one search input box upon entering the world search screen. This search bar also does not reappear when going back to the normal worlds screen.
This behavior only seems to affect the Worlds search screen, I could not get it to happen on any of the other search windows.
