title: layout_weight=".4" looks bigger than layout_weight=".6"
body: <p>This. I can't understand why first layout looks bigger than second layout if the last one has .6 (60%).</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:app="http://schemas.android.com/apk/res-auto"
      android:orientation="horizontal" android:layout_width="match_parent"
      android:layout_height="match_parent"&gt;
  
      &lt;RelativeLayout
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:layout_weight=".4" &gt;
  
      &lt;/RelativeLayout&gt;
  
      &lt;RelativeLayout
          android:layout_width="match_parent"
