title: transform scale(1) does not work in Microsoft Edge
body: <p>I have problems performing a simple transform: <code>scale()</code> in Microsoft Edge.
  I created a <a href="http://codepen.io/erotte/pen/KrBOvA" rel="nofollow">simple test case</a> that should show a submenu on hover via scaling the <code>scaleX()</code> property. This should work in any browser. 
  In Edge it fails as long as the value I like to scale to is 1, but works if it's 1.0001 or 0.999999, for example. This also fails with <code>scale()</code> and <code>scale3d()</code>. </p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>* {
    font: 18px/1.5 sans-serif;
  }
  li {
    padding: 0.2em 1.4em
  }
  .root &gt; li {
    display: inline-block;
    background: #adc;
  }
  li &gt; ul {
    position: absolute;
    background: #cde;
    transform: scaleY(0);
    border: 1px solid green;
    height: 200px
  }
  
  li.one:hover &gt; ul {
    transform: scaleY(1.0001) ;
  }
  
  
  li.two:hover &gt; ul {
    transform: scaleY(1.0) ;
  }
  
  li.three:hover &gt; ul {
    transform: none ;
  }
  
  
  .content {
    background: #fed;
    min-height: 700px;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;ul class='root'&gt;
    &lt;li class='one'&gt;hover me, it works
      &lt;ul&gt;
        &lt;li&gt;ding&lt;/li&gt;
        &lt;li&gt;dong&lt;/li&gt;
      &lt;/ul&gt;  
    &lt;/li&gt;
    &lt;li class='two'&gt;me not, in IE Edge
      &lt;ul&gt;
        &lt;li&gt;ding&lt;/li&gt;
        &lt;li&gt;dong&lt;/li&gt;
      &lt;/ul&gt;  
    &lt;/li&gt;
    &lt;li class='three'&gt;got it!
      &lt;ul&gt;
        &lt;li&gt;&lt;code&gt;transform: none&lt;/code&gt;&lt;/li&gt;
        &lt;li&gt;does the trick!&lt;/li&gt;
        &lt;li&gt;so stupid!&lt;/li&gt;
      &lt;/ul&gt;  
    &lt;/li&gt;
  &lt;/ul&gt;
  &lt;div class="content"&gt;
  &lt;h1&gt;Huhuuuh,&lt;/h1&gt;
    &lt;p&gt;Obviously IE Edge (current Version on a Surface Pro) has a problem with hiding and showing elements via a scale transforms to factor 1. As long as its not Integer(1) like 0.9999 or 1.0001, it works.
    &lt;/p&gt;
    &lt;p&gt;Just try out here and change the values to get sure.&lt;/p&gt;
  &lt;p&gt;
  My IE Version:
    &lt;br /&gt;
  Microsoft Edge 25.10568.0.0
  &lt;br /&gt;
  Microsoft EdgeHTML 13.10568.0.0  
    &lt;/p&gt;  
  &lt;/div&gt;</code></pre>
