Steps to reproduce

Load the admin

Expected behavior

No javascript errors happen

Actual behavior

Due to a missing comma here a javascript error occurs, causing requests made with the admin to fail with a CSRF error.

Is this related to #4471 ?
How can we reproduce the admin issue ? As you might see with #4471, it seems to be working.

Dammit, yup - needs resolving.
Same as #4435 but for the admin renderer.
Pull requests welcome.
