Fix issue with missing lock display.

Browse Source 
This was caused by a logic error concerning a lock state when thread t1
was waiting for a lock, thread t2 released the lock and thread t1 didn't
yet acquire a lock. High zoom level was needed.

(Threads are performing Wait, Obtain, Release operations on locks.)

           Problem

In the region marked by the problem line the lock count was 0, which
didn't trigger the appropriate code branch.
