Playlist: Remove block toolbar sharing between parent and child blocks

packages/block-library/CHANGELOG.md

@@ -11,6 +11,7 @@
 -   Icon: Apply only padding to the inner SVG in the editor, so margin is no longer applied twice compared to the front end ([#81292](https://github.com/WordPress/gutenberg/pull/81292)).
 -   Playlist Track: Mark track media fields as content so toolbar inserters add an empty track instead of duplicating the selected track.
 -   Tabs: Number the generated tab IDs from 1 and keep them sequential, so IDs generated by other blocks on the page no longer shift the numbering ([#81781](https://github.com/WordPress/gutenberg/pull/81781)).
+-   Playlist: Stop sharing the parent "Add track" toolbar control with selected Playlist Track child blocks ([#81432](https://github.com/WordPress/gutenberg/pull/81432)).
 -   Term Description: Apply the term description display filters when rendering with term context inside a Terms Query loop, so multi-paragraph descriptions keep their paragraphs and match the taxonomy archive rendering ([#81290](https://github.com/WordPress/gutenberg/pull/81290)).
 -   Accordion: Resolve the URL fragment with the `:target` pseudo-class instead of decoding `window.location.hash`, so a hash containing malformed percent-encoding no longer throws a `URIError` when a panel is opened ([#81780](https://github.com/WordPress/gutenberg/pull/81780)).
