get deviceSensorAuthorization(): Promise<WebPage_DeviceSensorAuthorization>@MainActor var deviceSensorAuthorization: WebPage.DeviceSensorAuthorizationAllows specifying how web resources may access device sensors. The default implementation returns `WKPermissionDecision.prompt` for all requests.
setDeviceSensorAuthorization(value: WebPage_DeviceSensorAuthorization): Promise<void>@MainActor var deviceSensorAuthorization: WebPage.DeviceSensorAuthorizationAllows specifying how web resources may access device sensors. The default implementation returns `WKPermissionDecision.prompt` for all requests.
get ignoresViewportScaleLimits(): Promise<boolean>@MainActor var ignoresViewportScaleLimits: BoolDetermines whether a webpage allows scaling of the webpage. When set to `true`, this property overrides the user-scalable HTML property in a webpage, and lets the webpage scale its view's content regardless of the author’s intent. The default value of this property is `false`.

setSupportsAdaptiveImageGlyph(value: boolean): Promise<void>@MainActor var supportsAdaptiveImageGlyph: BoolIndicates whether insertion of adaptive image glyphs is allowed. The default value is `false`. If `false`, adaptive image glyphs are inserted as regular images. If `true`, they are inserted with the full adaptive sizing behavior.

get defaultNavigationPreferences(): Promise<WebPage_NavigationPreferences>@MainActor var defaultNavigationPreferences: WebPage.NavigationPreferencesThe default preferences to use when loading and rendering content. Use this property to specify the JavaScript settings and content mode for new navigations. When the webpage navigates to a new resource, it passes the default preferences to its navigation decider, which can modify the preferences if desired.
setDefaultNavigationPreferences(value: WebPage_NavigationPreferences): Promise<void>@MainActor var defaultNavigationPreferences: WebPage.NavigationPreferencesThe default preferences to use when loading and rendering content. Use this property to specify the JavaScript settings and content mode for new navigations. When the webpage navigates to a new resource, it passes the default preferences to its navigation decider, which can modify the preferences if desired.
