Clear stack fail with fragmentHideStrategy = DETACH_ON_NAVIGATE_HIDE_ON_SWITCH

As title said, I set up Fragnav with this option: fragNavController.fragmentHideStrategy = FragNavController.DETACH_ON_NAVIGATE_HIDE_ON_SWITCH

Currently, I am on first bottom tab (Home) and try to pop all other stack to root fragment like this:

override fun popToRootFragment(tabIndex: Int?) {
        // Not works if tabIndex is not belong this current stack
        navController?.let {
            val stackIndex = tabIndex?.valid() ?: it.currentStackIndex
            it.clearStack(stackIndex)
        }
    }

    override fun popAllToRootFragment() {
        repeat(numberOfRootFragments) {
            popToRootFragment(it)
        }
    }

And after that, I click on other bottom tab, for example, MyPage -> it just show blank page.

I checked library core code, and saw that when clear stack with stackIndex = 2 (MyPage), this function addPreviousFragment() not add MyPageFragment, but try to add HomeFragment (root fragment of current stack). -> so when click on MyPage bottom tab after that, it show blank page, because all fragments of MyPage stack's removed and MyPageFragment be not attached yet. And I used fragmentHideStrategy = DETACH_ON_NAVIGATE_HIDE_ON_SWITCH, means just show fragment when switch tab.

This bug just happened with fragNavController.fragmentHideStrategy = FragNavController.DETACH_ON_NAVIGATE_HIDE_ON_SWITCH, but it works with DETACH or HIDE strategy. Do you think this is the library bug? Or am I wrong? Please check it and fix it as soos as possible. Thank you so much!
