When dispatching events to exceed the max size, the following occurs:
2026-03-25 11:56:12,915 - asyncio - ERROR - Exception in callback EventBus.dispatch()
handle: <Handle EventBus.dispatch()>
Traceback (most recent call last):

RuntimeError: io#00ca🟢(queue=0 active=0 history=10 handlers=2) history limit reached (10/10); set event_history.max_history_drop=True to drop old history instead of rejecting new events
However, this is contradictory to the README.md, which clearly states:
When max_history_size is set, EventBus automatically removes old events when the limit is exceeded
Additionally, following the exception's suggestion:
self.event_bus.event_history.max_history_drop=True
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'dict' object has no attribute 'max_history_drop'
The documentation and exceptions both contradict each other, and neither solution they propose works.
