Adapt to changes in HA Core PR 113798

Thanks for the notification on this. Do you know when this change will be released in Core? As a custom component I have to support backward compatibility to some degree and this breaks under my current target of 2023.11

[emontnemery]

This will be included in Home Assistant Core 2024.4.0, you need to set that as the minimum HA version when you've merged this.
You could also check the type of the parameter, something like this, for backwards compatibility:

if type(event_data) is Event:  # Intentionally avoid `isinstance` because it's slow and we trust `Event` is not subclassed
    event_data = event_data.data

Thanks for the pointer, I'm a fairly new custom component dev so this is the first breaking change I've had to deal with.
I'll type check until I can wean users off the old HA versions.
I see you reference this PR in issues on other repo's so good to have this option of handling it as a pattern.
