Panes do not correctly reflect Login status

[brownhoward]

If I am logged into a React SDK app (e.g., https://generator.inrupt.com), and then open my Profile in the same browser, I can edit any of the Profile fields (so I am clearly logged in and authorised), but below the Profile I see "Log in" and "Sign UP for Solid" buttons which seems to infer that the Data Browser does not think I am logged in.

To Replicate

1. Open https://generator.inrupt.com
2. Log in via the Login screen.
3. Display the Profile.
4. Edit a Profile field just to confirm I am logged in and authorised to edit the Profile.
5. Click the WebID link shown at the top of the Profile page.
6. A new browser tab opens, and the Data Browser Profile for the logged in user is displayed.
7. Edit a Profile field just to confirm I am logged in and authorised to edit the Profile.
8. Scroll down to the bottom of the Data Browser Profile page.

Expected Behaviour

1. "Log out" button displayed, illustrating I am logged in.

Actual Behaviour

1. "Log in" and "Sign Up for Solid" buttons are displayed.

Dev Notes

• If I click the "Log in" button, the standard Log in dialog is displayed. Selecting the appropriate log in method, a "Logged In!" message is displayed, but I am not prompted to enter a password.
