All of these steps occur in the side bar and involves 2 databases. The first database must have enough tables that you get the option to search them when clicked on in the side bar. The second database must not have enough to have the table search field when you click on it in the side bar. Go to the first database, open its table list, and enter something in the search field. Then go to the second database and open its table list you will notice the search has been applied to that database as well unfortunately since there aren't enough tables in this DB to give you a search field you cannot perform another search to recover them you have to refresh the page. My suggested fix would be either ensure that the search only applies to the database its for OR always display a search field so you can at least search for the table you can't see.
