使用viewpager2+fragment时，沉浸式失效

如题，使用viewpager2+fragment时，viewpager2使用FragmentStateAdapter，fragment生命周期不走setUserVisibleHint，在onResume和onPause中处理也不行。

但是当应用从后台返回前台后，沉浸式生效。

//失效
override fun setUserVisibleHint(isVisibleToUser: Boolean) {
super.setUserVisibleHint(isVisibleToUser)
"setUserVisibleHint----${isVisibleToUser}".loge()
mImmersionProxy.isUserVisibleHint = isVisibleToUser
}

override fun onResume() {
    mImmersionProxy.isUserVisibleHint = true
    super.onResume()
    mImmersionProxy.onResume()

}

override fun onPause() {
    mImmersionProxy.isUserVisibleHint = false
    super.onPause()
    mImmersionProxy.onPause()

}

Reproduce the issue using ViewPager2 with FragmentStateAdapter and inspect the fragment entry points shown: setUserVisibleHint, onResume, and onPause. Verify immersive mode behavior during page changes and after returning from the background; done means the correct fragment consistently applies immersive mode without relying on the app returning to the foreground.
