[dependabot]

Bumps @wordpress/block-editor and @types/wordpress__block-editor. These dependencies needed to be updated together.
Updates @wordpress/block-editor from 12.26.0 to 15.21.1

Changelog

Sourced from @​wordpress/block-editor's changelog.

15.21.1 (2026-06-16)

15.21.0 (2026-06-10)

Code Quality

• Add missing @types/react dependency. #78882.

Documentation

• Fix documentation typos and grammar (#78686).

Internal

• ListView: Compute the block visibility label once in ListViewBlock and pass it down to ListViewBlockSelectButton, removing a duplicated useSelect/getBlockVisibilityLabel call and clarifying that the label is exposed to assistive technology through the row's aria-describedby (#78640).
• Dependency updates (#77954).

15.20.0 (2026-05-27)

Bug Fixes

• ColorPanel: Theme CSS custom-property gradients are now decoded to their preset slug and persisted as a gradient block attribute rather than as a raw style.color.gradient value (#78328).

Internal

• Remove legacy Notice overrides in block placeholder notices and media replace flow error UI (#78231).
• Updated diff dependency from ^4.0.2 to ^8.0.3 (#77992).

15.19.0 (2026-05-14)

Enhancements

• BlockManager: Add stacking context isolation to category list (#77759).

Bug Fixes

• ColorPanel: Fix incorrect color selection and text↔link sync with duplicate-value palette entries. Slug-based selection is now threaded through the color panel so that two palette entries sharing the same hex value but different slugs are treated as distinct choices. The text↔link sync condition now compares raw stored references instead of decoded hex values; the previous decoded comparison incorrectly conflated entries that shared a hex value (#78048).

15.18.0 (2026-04-29)

Enhancements

• Use --wpds-cursor-control for interactive cursor styling and replace all instances (#77354).

15.17.0 (2026-04-15)

15.16.0 (2026-04-01)

15.15.0 (2026-03-18)
