Comment:

 In [changeset:"56960" 56960]:
 {{{
 #!CommitTicketReference repository="" revision="56960"
 Patterns, Templates: Inject `theme` attr into Template Part blocks.

 It was found that Template Part blocks were broken in the Site Editor,
 showing the `Template part has been deleted or is unavailable` message,
 due to a missing `theme` attribute.

 This bug seems to have been introduced by [56896], whose goal was to only
 inject that attribute into the markup returned by the templates and
 patterns REST API endpoints but not on the frontend, in order to improve
 performance. It has been demonstrated locally that reverting that
 changeset fixes the bug.

 Reverts [56896].
