Onclicklistener not working in part that get's added to view later

I have an onclicklistener on a layout, which contains two includes.
One of the includes contains a constraint layout which will be made visible on click of the container.
It should also be made invisible again, if I click on the layout again.
It works, if I click in the part that was always visible. However, if I click in the area of the newly added constraint layout, nothing happens.
The onclick-listener does not fire.
It works anywhere around the include though. E.g. clicking on the left of it (left there's a margin in original) it closes again.
Here are the (simplified) layouts:

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:bind="http://schemas.android.com/apk/res-auto"
    xmlns:card_view="http://schemas.android.com/apk/res-auto">

    <data>
      //Viewmodel
    </data>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

        <FrameLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:onClick="@{() -> viewModel.onClickItemContainer()}"
            android:clickable="true">

            <androidx.cardview.widget.CardView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
              >
                <androidx.constraintlayout.widget.ConstraintLayout
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:animateLayoutChanges="true">

                    <include
                        android:id="@+id/item_main"
                        layout="@layout/item_always_visible"
                        bind:viewModel="@{viewModel}"
                        bind:layout_constraintTop_toTopOf="parent"
                        bind:layout_constraintStart_toStartOf="parent"/>

                    <include
                        layout="@layout/item_details"
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content"
                        bind:viewModel="@{viewModel}"
                        bind:layout_constraintTop_toBottomOf="@id/item_main"
                        bind:layout_constraintStart_toStartOf="parent" />
                </androidx.constraintlayout.widget.ConstraintLayout>
            </androidx.cardview.widget.CardView>

        </FrameLayout>

    </LinearLayout>

</layout>

Included layout (that toggles on/off):

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools">
    <data>
        //Viewmodel
        <import type="android.view.View" />
    </data>

    <androidx.constraintlayout.widget.ConstraintLayout
        android:id="@+id/entry_details"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:visibility="@{viewModel.detailsVisible? View.VISIBLE : View.GONE}"
        tools:visibility="visible"
        android:clickable="false">

        <androidx.recyclerview.widget.RecyclerView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            app:adapter="@{viewModel.adapter}"
            app:layoutManager="androidx.recyclerview.widget.LinearLayoutManager"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="parent"
            android:clickable="false"/>

    </androidx.constraintlayout.widget.ConstraintLayout>
</layout>

I've tried around with clickable="false" in a couple of places in the included layout already, because I found that suggestion in another question, but it did not help anything.
If it was affecting the whole extended area (also cardview below include, e.g) I'd be thinking it's a bug with Android not adapting click areas to layout changes, but since I can trigger the listener by clicking on left and below included part, it must be something else.

The items used in the recyclerview are also set to clickable = "false":

<?xml version="1.0" encoding="utf-8"?>
<layout>
    <data>
    </data>
    <TextView
        android:id="@+id/detail_text"
        xmlns:android="http://schemas.android.com/apk/res/android"
        style="@style/Text.SecondaryText"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:clickable="false"/>
</layout>

Apparently that is a known issue with recyclerviews, that they catch the click event, because they use it for scrolling.
A number of solutions can be found here:
https://stackoverflow.com/questions/30419898/parent-click-event-not-firing-when-recyclerview-clicked
In my case, making the recyclerview untouchable is a reasonable approach, because all elements are already in another recyclerview, so they will never get chopped and instead fill out the space required.
