title: Rendering issue in Chrome with CSS border style
body: <p>So I have this table:</p>
  
  <p><img src="https://i.stack.imgur.com/GlH8H.png" alt="Rendered upgrade table"></p>
  
  <p>I have some JavaScript code that highlights the current plan the user is on, this then changes if they upgrade or downgrade.</p>
  
  <p>When the upgrade button is clicked and the page renders it produces unwanted side effects as shown below:</p>
  
  <p><img src="https://i.stack.imgur.com/fs5vc.png" alt="Upgrade table"></p>
  
  <p>It's almost as if it applies an extra <code>border-top</code> to every other <code>&lt;td&gt;</code> tag. Now when I refresh the page it works okay. To add to the confusion also when I don't add a <code>border-right</code> and <code>border-left</code> attribute it works fine when the 'Upgrade' or 'Downgrade' buttons are pressed.</p>
  
  <p><img src="https://i.stack.imgur.com/aNiFJ.png" alt="Upgrade table without border right and left"></p>
  
  <p>I've tested it in Firefox and Safari also, Firefox renders it okay but it's still producing unwanted side effects in Safari.</p>
  
  <p>Does anyone know why this is?</p>
  
  <pre><code>$('#' + params['current_plan']).addClass('current_pricing_plan');`
  $(".current_pricing_plan button").prop("disabled", true);`
  
  .current_pricing_plan {
  border-bottom: 2px solid #00a6cd!important;
  border-left: 2px solid #00a6cd;
  border-right: 2px solid #00a6cd;
  border-top: 2px solid #00a6cd!important;
  background-color: #f4f4f4;
  }
  </code></pre>
  
  <p>The first block of code is the JS and the second is the CSS, i'm using Rails so heres an example of one of the <code>&lt;tr&gt;</code>'s in the html.erb file.</p>
  
  <pre><code>&lt;tr id="750" class="current-pricing-plan"&gt;
    &lt;td&gt;&lt;strong&gt;£25&lt;/strong&gt;&lt;span class="smalltxt"&gt; /month&lt;/span&gt;&lt;/td&gt;
    &lt;td&gt;&lt;strong&gt;750&lt;/strong&gt;&lt;span class="smalltxt"&gt; mins&amp;nbsp;included&lt;/span&gt;&lt;/td&gt;
    &lt;td&gt;&lt;strong&gt;4p&lt;/strong&gt;&lt;span class="smalltxt"&gt; /min&amp;nbsp;thereafter&lt;/span&gt;&lt;/td&gt;
    &lt;td class="last-col"&gt;
      &lt;button class="btn smallbtn confirm_opener_750-25"&gt;
      &lt;span class="hidetextmobile"&gt;&lt;/span&gt;
      &lt;% if @account.billing_plan.inclusive_minutes &gt; 750 %&gt;
        &lt;span class="your-plan"&gt;Downgrade&lt;/span&gt;&lt;span class="your-plan-none"&gt;Your Plan&lt;/span&gt;
      &lt;% else %&gt;
         &lt;span class="your-plan"&gt;Upgrade&lt;/span&gt;&lt;span class="your-plan-none"&gt;Your Plan&lt;/span&gt;
      &lt;% end %&gt;
    &lt;/button&gt;
   &lt;/td&gt;
  &lt;/tr&gt;
  </code></pre>
