MacOS title bar and tabs overlapped with buttonless or transparent window decorations

When setting `window.decorations = "Buttonless"`, and pressing Cmd-T, first time it creates a new window, then doing it again creates a new tab in that newly created window in which the tab bar is overlapped with the terminal text.
When setting `window.decorations = "Transparent"`, the buttons and title bar just overlapped with the terminal text anyway.
I am running MacOS 26 so I'm not sure if this issue is on older versions.
