Body

I'd like to suggest a small UI improvement that could significantly enhance the Pull Request review experience.

Currently, when reviewing a large Pull Request with many changed files, the top navigation tabs (Conversation, Commits, Checks, and Files changed) scroll out of view. If I need to switch between these tabs, I have to scroll all the way back to the top of the page.

This becomes especially inconvenient for large PRs containing dozens or hundreds of files, where reviewers frequently need to move between Files changed, Conversation, and Checks.

Suggested improvement:

Make the Pull Request navigation bar sticky (fixed) once the user starts scrolling.
Keep the tabs visible at the top of the viewport until the user reaches the end of the page.
Ensure the sticky header doesn't interfere with the existing file diff toolbar.

Benefits:

Faster navigation between PR sections.
Improved reviewer productivity, especially for large PRs.
Reduced unnecessary scrolling.
Better overall user experience during code reviews.

I've attached a screenshot highlighting the navigation bar that could remain visible while scrolling.
