Control the textarea value from keyed comment text.
openCommentForEdit updates the keyed text while CommentAnnotation can remain mounted. defaultValue does not update the mounted textarea, so Save can submit the previous contents. Derive isEmpty from the same controlled value.
🐛 Suggested fix
- const [isEmpty, setIsEmpty] = useState(!(text ?? initialText)?.trim());
+ const currentText = text ?? initialText ?? "";
+ const isEmpty = !currentText.trim();
...
- defaultValue={text ?? initialText}
+ value={currentText}
...
- setIsEmpty(!e.currentTarget.value.trim());
setText(e.currentTarget.value);Source: Learnings

[Medium risk] Refactors comment state to persist across diff refreshes. The PR is not ready to merge because staged and unstaged views can share a composer, refreshed annotations can point to the wrong code, and dismissed overlay text can reappear.

Comment:
**Staged comments share state** When a file has both staged and unstaged changes, the review renders two diffs, but both use this task-and-path key. Opening an inline comment in one diff also opens its selection and text in the other, where the same line number can refer to different code. Include the staged state in the key.

Comment:
**Refresh can misplace comments** If a refreshed patch moves or removes lines, the old numeric selection and annotation remain attached to the new diff. An unfinished comment can then appear on different code or have no valid line. Preserve the text, but remap or validate the line range when the patch changes.

Comment:
**Dismissed text reappears** The editor selection overlay uses this composer but only closes the overlay on dismissal; it does not clear the new text store. After a reviewer discards or submits a comment, the next comment on that file opens with the old text. Clear the stored text on overlay dismissal or keep that composer's text local.

undefined when no comment text is stored, and the new test expects it. The repository requires null, rather than undefined, for an intended absent result. Return null and update the test to satisfy that requirement before merging.
Rule Used: Use 'null' instead of 'undefined' to indicate an intended lack of result in functions. (source)

Comment:
**Exported hooks lack return types** The new exported hooks return objects without explicit return types. The repository’s TypeScript guidance requires explicit return types; declare their public return contracts before merging.
