Overview

This PR reserves right-side titlebar control space whenever window controls are on the right, and adds unit coverage for the helper that decides whether tab-bar space should be reserved.

Concerns

• This is a user-visible titlebar layout change, but the PR does not include screenshots or a video showing the Windows/Linux titlebar spacing. For faster review, please upload screenshots or a video of the feature working end to end.

Overview

This PR changes tab-bar layout so right-side custom window controls always reserve space while left-side controls retain the existing behavior, with direct unit coverage for the new helper.

Concerns

• This is a user-visible titlebar layout change, but the PR does not include screenshots or a short video. For faster review, please upload screenshots or a video showing the Windows/Linux titlebar controls and toolbar controls no longer overlap end to end.
