DialogFragment example something wrong on Android 6 Marshmallow emulator

Its a example to implement DialogFragment. Please check the screenshots of running on Android Emulators of Android 4.1 Jelly Bean with API 16, Android 5.1 Lollipop with API 22 and Android 6.0 Marshmallow with API 23. If the emulator of Android 6.0 Marshmallow work properly, DialogFragment display wrong on Marshmallow.

layout/fragment_dialog.xml, DialogFragment layout.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
 
 android_padding="10dp"
 android_orientation="vertical"
 android_layout_width="match_parent"
 android_layout_height="match_parent">

 <ImageView
 android_layout_width="wrap_content"
 android_layout_height="wrap_content"
 android_src="@mipmap/ic_launcher"/>

 <TextView
 android_id="@+id/dialogtext"
 android_layout_width="match_parent"
 android_layout_height="wrap_content"
 android_textSize="20dp"
 android_textStyle="italic|bold"/>

</LinearLayout>

MainActivity.java with DialogFragment.

package com.blogspot.android_er.androiddialogfragment;

import android.app.DialogFragment;

public class MainActivity extends AppCompatActivity {

 EditText inputTextField;

 @Override
 protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);

 inputTextField = (EditText)findViewById(R.id.inputtext);
 Button btnOpen = (Button)findViewById(R.id.opendialog);
 btnOpen.setOnClickListener(new View.OnClickListener() {
 @Override
 public void onClick(View v) {
 showDialog();
 }
 });
 }

 void showDialog() {
 FragmentTransaction ft = getFragmentManager().beginTransaction();

layout/activity_main.xml, main layout.

<?xml version="1.0" encoding="utf-8"?>

To fixed it, edit layout/fragment_dialog.xml, modify android:layout_width of <ImageView> from "wrap_content" to "match_parent".

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
 
 android_padding="10dp"
 android_orientation="vertical"
 android_layout_width="match_parent"
 android_layout_height="match_parent">

 <ImageView
 android_layout_width="match_parent"
 android_layout_height="wrap_content"
 android_src="@mipmap/ic_launcher"/>

 <TextView
 android_id="@+id/dialogtext"
 android_layout_width="match_parent"
 android_layout_height="wrap_content"
 android_textSize="20dp"
 android_textStyle="italic|bold"/>

</LinearLayout>

android:layout_width="wrap_content"

android:layout_width="match_parent"
