Control Clouds - not working with the 2024-04-09 version

[LMS235]

Issue Description

Since the current version 2024-04-09 (at least that's where I noticed it), the cloud display (https://www.dokuwiki.org/plugin:struct:cloud) no longer works.

here is our code

---- struct cloud ----
schema: schema
field: field
page
target: namespace:site
limit: 20
summarize: yes
----

The page simply remains empty. Everything else (table view etc.) works without problems, it only affects the cloud view.
