What issue are you seeing?

In the review/diff pane, opening an inline comment box causes the view to jump to the end of the document. The chat also takes focus when I open the comment box. Submitting the comment causes another jump to the end.

This loses my position in the diff and interrupts line-by-line review.

What steps can reproduce the bug?

1. Open a project with changes and open the review/diff pane.
2. Scroll to a section above the end of the document.
3. Open an inline comment box on a line.
4. Observe that the chat takes focus and the review view jumps to the end of the document.
5. Enter and submit the comment.
6. Observe that the review view jumps to the end again.

These observations are from manual use; no automated reproduction or root-cause verification has been performed.

What is the expected behavior?

Opening an inline comment should focus its text box and preserve the current position in the diff. Submitting the comment should also preserve that position, so review can continue from the same lines.

This report identifies a specific trigger: opening or submitting an inline review comment, with chat taking focus when the comment box opens. It is not yet confirmed whether these reports share a root cause. The focus transfer is an observed symptom, not a confirmed explanation for the scrolling.

Start by reproducing the issue in the review/diff pane using the six steps described, including opening and submitting an inline comment above the document end. No source file or test is named; done means the comment box receives focus and both opening and submitting preserve the current diff position without moving focus to chat.
