Comment (by westonruter):

 In [changeset:"39181"]:
 {{{
 #!CommitTicketReference repository="" revision="39181"
 Customize: Store modifying user ID with setting change written into
 changeset and restore current user when setting is being saved.

 Restoring the current user context when saving a setting ensures filters
 apply as expected, such as Kses. When a user is not associated with a
 given setting change, continue to override `capability` to be `exist` when
 saving. Skip overwriting setting values in a changeset that have not
 changed, facilitating concurrent editing and amending a changeset by a
 user with fewer privileges.

 See #30937.
 Fixes #38705.
