A BrowserSetting
object which determines whether the browser's context menu is shown on the mouseup event or on the mousedown event.
Its underlying value is a string that may be either "mouseup" or "mousedown".
The default value is "mouseup" on Windows, and "mousedown" on macOS and Linux. Assigning to it on Windows has no effect - the setting is only designed to allow the context menu to be opened on mouseup instead of mousedown, not the inverse.
