fix: add publishing workaround so that a page link can load

Loading the publishing app with a journal page link e.g. #/page/00000001-2025-0901-0000-000000000000
failed with "Error: 139 is not ISeqable". Weirdly :block/tags in
publishing app is returning integers instead of set of integers while
the app loads. This was encountered before in
