## 12.1.2

### Fixes
- Inline formatting — including superscript and subscript — is now reliably carried to the new paragraph on Enter and across block splits, including splits that occur past a trailing line break.
- A pending springloaded format is now honored when formatting is carried across a block split, so toggling a format off just before a split is respected in the new block.
- When a delete empties a block, the caret now stays in that block instead of moving elsewhere.
- After a deletion the caret keeps backward gravity, so formatting queried at the caret reflects the text that remains.
- The selection now collapses after paste and delete operations.
- The formatting-property registry is now thread-safe.
- Materialized elements are now held strongly from their document node, preventing them from being collected while still referenced by the live tree.
