There was an exception due to calling Object.keys on an undefined value
that caused a promise to fail to resolve.
This resulted in 'loading' not getting set to false, and the change was
never visible.
Compounded with this error is the fact that gr-error-manager did not
pick up on this exception, because unhandledrejection does not work in
Edge (or firefox), which is used in gr-reporting to catch errors.
