As expected.

There's no way to get events for this case without doing load detection in the
hotplug polling.  We don't currently support that case as load detection has
the potential to cause flicker on connectors that share resources.  If you need
it, you can remove the !force checks in the connector detect functions, but you
may get flicker on other connectors if they share resources.

> Events on connect only when I plug in the adapter with DDC.

As expected.
