patricialor@,Could you please take a look and reassign to the right owner if it is not related to your change.

Since it is regressed recently, adding 'Release block stable' label to this issue.

Thanks..!!

Thanks for the report! The bisect is correct. This behaviour is intended, though I didn't realise it would also affect added patterns in Site Settings. The real fix is to remove the link to Site Details on patterns from the site lists, but this only appears when #enable-site-settings is turned on, so I don't think it's a release blocker.
