🟡 Changes recommended

The new min-w-[12rem] can override the viewport-based max-w on very narrow viewports, potentially reintroducing horizontal overflow.

Once you've addressed the issues Copilot identified, you can request another Copilot review.

Pull request overview

Adjusts the ChangeHistory dropdown panel sizing so it no longer uses a fixed width, instead sizing to its content while remaining bounded by the viewport, addressing the UI concern raised in #9145.

Changes:

• Switches the dropdown wrapper from a fixed width (w-[26rem]) to content-based sizing (w-max).
• Updates the max-width constraint to cap at min(26rem, 100vw - 2rem).
• Introduces a minimum width (min-w-[12rem]) for baseline readability/consistency.
