WebKit shouldn't be modifying the value of UIApplication.idleTimerDisabled because we're a framework. The hosting application can rely on this flag to prevent screen sleep and it is not good for WebKit to be potentially overriding a value set by the application. To address the issue, the UIKit code indicates that frameworks are expected to call the `_setIdleTimerDisabled:forReason:` SPI instead.
