Buttons not clickable when placed at top of window with TitleBarStyle.hidden on macOS Tahoe (26.0)

When using TitleBarStyle.hidden on macOS Tahoe, placing any button at the top of the window makes it unclickable. The invisible title bar seems to overlap the window content and blocks click interaction.

The back button on the screenshot is unclickable:

.setAsFrameless allows to pass clicks through, but mouse cursor hover doesn't work properly.

Combination of both: .setAsFrameless and TitleBarStyle.hidden gives the desired behavior.
