What happened

The layout's corners setting was not one of the two styles. A window's corner radius cannot be resolved from an unreadable value, so the layout uses "rounded", its default (today's look). A value that is not a string is described by its type rather than printed, because printing it would risk a throw inside the warning itself.

The fix

Set corners to 'rounded' or 'square'.

The smallest fix

createLayout(el, { corners: 'square', windows: [ … ] });
