> @yanxinyi View's not getting deleted while parent was dropped has
something to do with SYSTEM.TASK? Do we save some intermittent state while
dropping view in SYSTEM.TASK?
Yes. The test issued a cascade drop and then force SYSTEM.TASK to run;
however, it might be the race condition that SYSTEM.TASK already started and
caused race condition. Changing the running interval config to the max value
can avoid this behavior.
