Reproduced on demo.sourcegraph.com

This has been reproduced on demo:

1. Go to https://demo.sourcegraph.com/contexts
2. Select the //app/main/core context

Expected behavior:

You can edit and delete a context that begins with a /

Actual behavior:

If you create a context that begins with a slash (or more than one slash), you can select it and search against it, but you cannot edit it or delete it.

There is slightly different behavior when it's a personal/org context vs global. But in both cases you cannot view, modify or delete the context.
