Current/Missing Behavior

When opening a window with frame: false and resizable: false, the rounded corners that are applied to windows in windows 11 disappear. They work fine when either of these options are set to true.

Expected/Proposed Behavior

Windows 11 rounded corners work regardless of frame and resizable options. An option to specify whether or not to disable them could also be a consideration.
