• Component used: Navigation
• Version used: 2.4.0-alpha04
• Devices/Android versions reproduced on: Pixel 4 Android 11 Emulator

When you use navigation component 2.4.0-alpha04 in combination with a BottomNavigationView, create 2 actions with an enterAnim, call these in 2 different tabs and then navigate between them, you'll see the enter animation while switching between tabs which looks weird. Weirdly, when you have a destination open with this animation in just 1 tab, navigating between tabs don't show this enter animation.

This can be reproduced quite easily: create a bottom navigation component application in Android Studio, change the version to 2.4.0-alpha04, add the safe args plugin and add any actions inside the fragments with an enterAnim:

<fragment
        android:id="@+id/navigation_home"
        android:name="com.cristan.bottomnavigationapp.ui.home.HomeFragment"
        android:label="@string/title_home"
        tools:layout="@layout/fragment_home">
        <action
            android:id="@+id/myTestAction"
            app:destination="@id/test_fragment"
            app:enterAnim="@android:anim/slide_in_left" />
    </fragment>

    <fragment
        android:id="@+id/navigation_dashboard"
        android:name="com.cristan.bottomnavigationapp.ui.dashboard.DashboardFragment"
        android:label="@string/title_dashboard"
        tools:layout="@layout/fragment_dashboard">
        <action
            android:id="@+id/myTestAction2"
            app:destination="@id/test_fragment"
            app:enterAnim="@android:anim/slide_in_left" />
    </fragment>

    <fragment
        android:id="@+id/test_fragment"
        android:name="com.cristan.bottomnavigationapp.ui.notifications.NotificationsFragment"
        tools:layout="@layout/fragment_notifications" />

Note that I open the same Fragment in the 2 tabs to make this easily reproducable, but this also happens when I open different fragments in the tabs.
