IUmbracoContext

has a number of nullable properties, including

Content

and

Media

for the content cache and media cache respectively. https://github.com/umbraco/Umbraco-CMS/blob/contrib/src/Umbraco.Core/Web/IUmbracoContext.cs#L37-L42 I've never experienced these being null, and I can find any information on in which situations they can be null. Anyone with a bit of insight into this?
