Resolves

Fixes #7113

Proposed Changes

Calls updateDisabled if the block is disabled during the render call for a block.

The reason this happened in JSON and not XML is that XML sets the disabled state after rendering. JSON sets it before rendering. When the block was eventually rendered in JSON, it looked correct because it had the correct enabled property, but the visuallyDisabled property was not set (because the block was not rendered at the time of the original updateDisabled call). So this just calls that function again during render which updates the state as needed.

Behavior Before Change

See detailed reproduction steps in linked bug. If you loaded from json, the block would look and be disabled, but the block's visuallyDisabled property was not set. So the visual state would be out of sync with the actual state of the block.

Behavior After Change

Disabled blocks loaded from json behave as expected.
