[Bug]: Browser preview corners extend outside the glass frame when maximized

Before submitting

• I searched existing issues and did not find a duplicate.
• I included enough detail to reproduce or investigate the problem.

Area

apps/desktop

Steps to reproduce

1. In T3 Code Nightly on Windows, have an agent use the browser.
2. Pop out the browser preview.
3. Expand/maximize the preview.
4. Inspect the preview corners. The bottom-left and bottom-right corners are the easiest to see and are marked with red arrows in the screenshot.

Expected behavior

The page and its scrollbars should stay contained within the rounded glass frame.

Actual behavior

The page/scrollbar edges extend slightly outside the rounded glass frame at the preview corners. This affects more than the bottom corners; those are just the easiest to see in the screenshot. Small visual bug; no functional issue is being reported.

Impact

Cosmetic issue

Version or commit

T3 Code Nightly. Installed Windows executable reports version 0.0.41.0; full nightly build identifier was not captured.

Environment

Windows 11 25H2, build 26200.9445; T3 Code desktop app.

Screenshot

Private content is covered with opaque frosted-style panels. The preview corners, scrollbars, and red arrows are unchanged from the original screenshot.

Begin in apps/desktop and reproduce the issue on Windows by opening an agent browser, popping out its preview, and maximizing it. Inspect the preview frame and its page or scrollbar edges against the provided screenshot; done means all corners remain contained within the rounded glass frame without visual overflow.
