How to animate Android Navigation Architecture fragment as sliding over old fragment?

In example navigation action defined in navigation graph:

<action
    android:id="@+id/action_fragment1_to_fragment2"
    app:destination="@id/fragment2"
    app:enterAnim="@anim/right_slide_in"
    app:popExitAnim="@anim/left_slide_out"/>

When Fragment2 opens and starts sliding into view from the right, Fragment1 disappears instantly (sadly). When Fragment2 is closed and starts sliding to the right, Fragment1 is nicely visible under it, giving a nice stack pop effect (comparable to iOS).

How can I keep Fragment1 visible while Fragment2 slides into view?
