- When the default renderer is an Ajax renderer, don't replace the URI. For example, when viewing a Jupyter notebook, the URI should remain /F123, not instantly change to /view/123/jupyter/.
- Fix an issue where non-ajax renderers could fail to display the dropdown menu properly.
- Viewed a Jupyter notebook, stayed on the same URI.
- Changed rendering, got different URIs.
- Viewed a JSON file and toggled renderers via dropdown.
