Live update does not always trigger when updating subelements

[Adjective-Object]

Because we only listen to the row itself, the only change events that trigger a re-render are property additions / changes or adding / removing children.

We can fix this by doing a walk of all Block children when opening up subscriptions & on the subscription update. This might be something we could add to the notion-py module itself and PR in.

I can't reproduce this consistently. Maybe I'm wrong? Maybe it has to do with nesting the elements under other elements? Its hard to tell.
