Dynamic plugin extensions disappear from the UI when an error is encountered loading a code reference.

4.11

1. A dynamic plugin is installed, enabled, and provides an extension where a codeRef fails to load. 
2. An interaction occurs with the extension, and the console attempts to reference the extension codeRef. 
3. The extension codeRef fails to load  

The extension component disappears from the console. The component will not re-appear unless the plugin is manually re-enabled, which starts this cycle over.

This can probably be easily reproduced by adding an intentionally "broken" extension to the demo dynamic plugin, then following the steps above
