Member variable CoreWebView2Settings():IsNonClientRegionSupportEnabled Foundation
Controls whether non-client region support is enabled.
This member variable determines whether web content can define non-client regions using the CSS property "-webkit-app-region". Non-client regions allow web content to specify areas that should be treated as window dragging regions or title bar areas in frameless windows. When set to .T. (true), this functionality is enabled. When set to .F. (false), the CSS property has no effect. By default, non-client regions support is disabled.
