joinItemForward used joinPoint, which will join two isolating frames. ListKeymap Delete hit that path and swallowed the next frame.

Both join item commands now skip a join when either sibling is isolating. Delete stays inside the frame, and two list items in the same frame still join.

Fixes #8321

📝 Summary

Summary

  • Prevent joinItemForward and joinItemBackward from joining across isolating: true nodes.
  • Keep Delete operations inside the current frame.
  • Preserve joins between list items and paragraphs in the same frame.
  • Add unit and integration tests for isolating frames.
  • Add a patch changeset for @tiptap/core.

Walkthrough

joinItemForward and joinItemBackward now check isolating boundaries before joining. Unit and integration tests cover regular joins, rejected joins, and ListKeymap Delete behavior.

Changes

Isolating-aware item joins

Layer / File(s) Summary
Join boundary validation
packages/core/src/commands/canJoinItemsAt.ts, packages/core/src/commands/joinItemForward.ts, packages/core/src/commands/joinItemBackward.ts
Adds shared validation for isolating boundaries and applies it before forward or backward joins.
Join command coverage
packages/core/src/commands/joinItemForward.test.ts
Tests successful joins between regular containers and rejected joins across isolating containers.
List delete integration coverage
packages/extension-list/tests/integration/listKeymapIsolatingDelete.test.ts, .changeset/join-items-isolating.md
Tests that Delete joins content within one isolating frame and preserves later frames. Adds the patch changeset.
