[Live Component] Data Model Updates for Live Component Form with Nested Entities

[Precipitator80]

I have a Live Component with the ComponentWithFormTrait. In this component I have an entity with a LiveCollection of other entities, say a BlogPost entity with UserComments. If I want to run code linked to BlogPost title changes, I can use data-model on the form type in conjunction with keys writable: ['title'] and onUpdated: ['title' => 'processTitle'] in the Live Component code. However, I cannot do this with, for example, the body of a UserComment. This is due to the data being too complex to bind. Is there a good way of working around this issue so that I can trigger Live Component PHP code when UserComment fields change?

I believe this may be a related issue #2290 .
