+- [#298](https://github.com/devgateway/data-viz-ui/pull/298) [`dc8a212`](https://github.com/devgateway/data-viz-ui/commit/dc8a212c4e56fae08ad9cb697dd91d9cbe8c209d) Thanks [@claude](https://github.com/apps/claude)! - Revert the PR #296 fix for TCDICORE-601, which comma-joined all array/object
+  attributes in `PreviewComponent.tsx` before postMessage'ing them to the
+  block-editor preview iframe. That change was a shared choke point used by
+  every embeddable block, and it broke any block whose attribute is an array of
+  objects (e.g. `filters`, map `legendBreaks`) by turning it into an
+  unparseable `"[object Object],[object Object]"` string.
+
+  `PreviewComponent.tsx` now always JSON-stringifies object/array attributes
+  again, restoring pre-PR-296 behavior for every block except Tabbed Posts.
+
+  The original TCDICORE-601 problem — the Tabbed Posts editor preview sending
+  `categories` as `"[5,7]"` instead of the front-end's comma-separated `"5,7"`
+  — is now fixed locally inside the Tabbed Posts embeddable component
+  (`tabbedposts/index.jsx`), which detects a JSON-array-shaped `categories`
+  string and normalizes it to the comma-separated format the REST API expects,
+  without changing how any other block's attributes are serialized.
