The latest preview version of RStudio server includes the quarto render button. However, when I render an example document (e.g. from `New Project` -> `Quarto Project`). The html output is displayed verbatim in the viewer pane instead of rendered:

If I click the little `show in new window` button the browser also still shows it as text in a new tab. 
Tested on brave, chrome and firefox.

The developer console in frefox shows:
`The resource from “http://<myserversname>:8787/p/1d4fe537/quarto-te...” was not rendered due to an unknown, incorrect or missing MIME type (X-Content-Type-Options: nosniff).` and links here: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/X-Content-Type-Options

whereas brave / chrome doesn't tell us more: `Failed to load resource: the server responded with a status of 500 (Internal Server Error)`
