Angular Flex Layout - Not working : <p>I tried to use 2.0.0-beta.9 in my app, a simple test doesn't work </p>

<pre><code>&lt;div fxLayout="row"&gt;
    &lt;div&gt;1. One&lt;/div&gt; &lt;div&gt;2. Two&lt;/div&gt; &lt;div&gt;3. Three&lt;/div&gt; &lt;div&gt;4. Four&lt;/div&gt;
&lt;/div&gt;
</code></pre>

<p>displays columns instead of rows</p>

<p>I think I am importing the library properly</p>

<pre><code>import {Component, NgModule} from '@angular/core'
import {BrowserModule} from '@angular/platform-browser'

import {FlexLayoutModule} from "@angular/flex-layout";

import {TestApp} from "./test-app";

@NgModule({
  imports: [ 
    BrowserModule,
    FlexLayoutModule
  ],
  declarations: [ TestApp ],
  bootstrap: [ TestApp ]
})
export class TestAppModule {

} 
</code></pre>
