@alamb I've found the bug and fixed this behavior. Although this is one of
those scenarios where I'm somewhat questioning how it ever worked correctly in
terms of switching modes using commands. Regardless, I'm glad you chose to run
a functional test case that I clearly had not run! The issue seems to have been
with the initial command to change the state. Curiously, once the profiling had
been enabled one time the changes thereafter seemed to work as expected. With
the bug fix, the initial command now seems to be working though.
