Force update clarification on attributes

| force_update | `bool` | `False` | Write each update to the state machine, even if the data is the same. Example use: when you are directly reading the value from a connected sensor instead of a cache. Use with caution, will spam the state machine. |

I’m not completely sure what “each update” means here.

For example:

I have an entity that updates its state at regular intervals (say, once per hour).

This entity also has attributes that may update independently of the main state.

So If I enable force_update:

1. Every scheduled state update generates a new state change event, even when the new state value is the same as the old one. This is clear, but
2. If an attribute changes between two state updates, does the attribute change also trigger a state change event because of force_update, or is "force update" only tied to the state value itself?
