-------------------------------------------------------------------
Not a bug, the component behaves correctly, it's a RESET event after all. It
would be a nice thing to have though. You don't have to force the search on
each reset, it can be avoided by a flag (defaulting to false) but there are
many use cases where even a linear search would not pose a significant
performance penalty.
Anyway, this is not of a high priority.

Anyway, this should be moved to feature requests, or at least the severity of
it lowered.
