Snackbar's action Gravity

Question

I'd like to display a Snackbar in my Activity. It works fine on my phone (Oneplus One CM13), however for some reason on the tablet (Nexus 7 2013 LineageOS 14.1 android 7.1.1) the action Button is displayed right after the Snackbar's text TextView (with some padding and margins).

Phone:

Tablet:

After turning Show layout bounds on, I've noticed that on the phone the TextView takes up the whole remaining space (which makes sense), and on the tablet it just wraps it's content with about 16dp of margin on the right.

Phone with layout bounds:

Tablet with layout bounds:

I've tried to change the Gravity of the action Button using the LayoutParams but it didn't work. I didn't modify the Snackbar in any way (except when trying to fix the problem). The Activity is a freshly created Empty Activity using Android Studio 2.3.

EDIT: Here's the full XML layout (fully generated by Android Studio):

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
    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"
    android:id="@+id/coordinator"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.roundel.csgodashboard.ui.activity.SnackbarTestActivity">

    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/AppTheme.AppBarOverlay">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            app:popupTheme="@style/AppTheme.PopupOverlay"/>

    </android.support.design.widget.AppBarLayout>

    <android.support.design.widget.FloatingActionButton
        android:id="@+id/fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|end"
        android:layout_margin="@dimen/fab_margin"
        app:srcCompat="@android:drawable/ic_dialog_email"/>

</android.support.design.widget.CoordinatorLayout>

How are you adding the TextViews/Snackbar (programmatically or another xml) and populating them? — Doron Yakovlev Golani, Mar 28 '17 at 18:47
I'm using the standard way of showing a Snackbar ```Snackbar.make(v, "Test", Snackbar.LENGTH_LONG).setAction(...).show();```, where v is the FAB — Krzysztof 'RouNdeL' Zdulski, Mar 28 '17 at 18:48
Snackbar is not a Toast, you pass a `View` into it, it will then traverse the view tree trying to find a CoordinatorLayout. Look at the [docs](https://developer.android.com/reference/android/support/design/widget/Snackbar.html) — Krzysztof 'RouNdeL' Zdulski, Mar 28 '17 at 18:57
