[system test] UI contains stale index information - continues to display dropped indexes as still a part of the system

created an index default(p2) before loading all the bucket data.
create index p2 on default(name) using gsi

• after all the data was loaded, decided to drop the index p2.
  Drop index stmt goes through successfully.

• select * from system:indexes where keyspace_id="default" - shows this index no longer exists

The UI ( attached screenhot) continues to display the dropped index -
I waited for over an hour, did multiple other server operations like - restart couchbase service, issue queries - waiting for the index UI to eventually catchup

But it never does - Both the Index page and the main UI continues to display stale p2 index data.
