Expected behavior

Documentation here should indicate that when KeyLoader is implemented, LoadKey is called before Load. Also, it should note that if an error occurs in LoadKey, Load is still called, but the LoadKey error takes priority to return.

Actual behavior

Documentation indicates LoadKey is called after Load and makes no mention of error handling.

Additional context

The behavior was intentionally changed to the expected behavior above in #1575, but documentation was not updated.
