Increase default inactivityTimeout from 2 seconds to 5

When using VoiceOver in iOS, the user has to single-click an item to select it and then double-click it to interact with it. This series of actions takes more time than the allotted 2s that is set in the inactivityTimeout. Because of this, the non-native controls collapse before the user has a chance to select and interact with the controls. By increasing the default inactivityTimeout, we are giving the user a little more time to accomplish their goals.
