Comment 11 for bug 1603458

Test it with Queens dashboard and meet with the same issue that we cannot delete the lb.

When I followed the above steps:
* in "Load Balancers" click on the name of the LB (e.g. "lb1")
* go to "Listeners" tab, click on the name of the listener
* click on the link shown next to "Default Pool ID" (this is the trick!)
* click on the link shown next to "Health Monitor ID"

At this step, there is no button to delete Health Monitor.:-( Thus the associated listener could not be deleted, which fails the lb deletion.
BTW, CLI deletion works well though.
