innsida-custom-css.user.js inserts iframe on all innsida.ntnu.no-subpages

[marvik]

innsida-custom-css.user.js affects subpages like:
https://innsida.ntnu.no/forms
whereby it inserts the co-pilot chat that usually only appears on the innsida.ntnu.no news feed on all other subpages.

When testing the above url, make sure you log in to observe copilot being inserted to the forms login page.
