Window controls overlap with toolbar buttons on Windows

What's Wrong?

On Windows, the app's toolbar buttons (hamburger menu, copy, search, back/forward) are positioned at the top-left of the window, but they overlap with the Windows system window controls (close, minimize, maximize). As a result, some toolbar buttons are hidden behind the system controls and cannot be clicked.

Additionally, the sidebar appears collapsed by default after reinstalling the app, with no visible way to restore it since the toggle button is inaccessible.

Workaround found: Ctrl+/ restores the sidebar.

Environment: Windows 11

What Should Happen?

Toolbar buttons and window system controls should not overlap.
