What problem does this address?

The inspector fields currently doesn't support Pattern Overrides or any other attributes that have block bindings.

To reproduce this:

1. Insert a synced pattern that has overrides
2. Note that the inspector fields are displayed and can be edited, however any changes aren't persisted.

What is your proposed solution?

The reason behind the issue is that block bindings hooks into (or monkey patches) a block's setAttributes calls.

The inspector fields instead dispatch the updateBlockAttributes action, which doesn't have any handling of block bindings.
