title: adding 'nofollow' to my amazon affiliate links breaks the link
body: <p>So, this is driving me insane.<br>
  On my website <a href="http://http://danidolldesigns.com/resources/bullet-journal-resources/" rel="nofollow noreferrer">http://http://danidolldesigns.com/resources/bullet-journal-resources/</a> I was attempting to add a bunch of amazon affiliate links. I have been using the 'text only' option amazon offers when creating the link.<br>
  I copy and paste the link into my webpage, which works fine. But as soon as I edit the code to add 'nofollow' to it, it changes the link to a webpage that doesn't exist...example below:  </p>
  
  <p>original code:  </p>
  
  <pre><code>    &lt;a href="https://www.amazon.co.uk/gp/product/B000WH2X10/ref=as_li_tl?ie=UTF8&amp;amp;camp=1634&amp;amp;creative=6738&amp;amp;creativeASIN=B000WH2X10&amp;amp;linkCode=as2&amp;amp;tag=danidolldes06-21&amp;amp;linkId=5e049dc32f974304c20e04c605e1232a" target="_blank" rel="noopener"&gt;Faber-Castell Water Colour Pencils (Pack of 24)&lt;/a&gt;    
  </code></pre>
  
  <p>but when changed to:</p>
  
  <pre><code>    &lt;a href="https://www.amazon.co.uk/gp/product/B000WH2X10/ref=as_li_tl?ie=UTF8&amp;amp;camp=1634&amp;amp;creative=6738&amp;amp;creativeASIN=B000WH2X10&amp;amp;linkCode=as2&amp;amp;tag=danidolldes06-21&amp;amp;linkId=5e049dc32f974304c20e04c605e1232a" target="_blank" rel="nofollow noopener"&gt;Faber-Castell Water Colour Pencils (Pack of 24)&lt;/a&gt;
  </code></pre>
  
  <p>the link then sends you to "danidolldesigns.com/"<a href="https://www.amazon.co.uk/gp/product/B000WH2X10/ref=as_li_tl?ie=UTF8&amp;camp=1634&amp;creative=6738&amp;creativeASIN=B000WH2X10&amp;linkCode=as2&amp;tag=danidolldes06-21&amp;linkId=5e049dc32f974304c20e04c605e1232a" rel="nofollow noreferrer">https://www.amazon.co.uk/gp/product/B000WH2X10/ref=as_li_tl?ie=UTF8&amp;camp=1634&amp;creative=6738&amp;creativeASIN=B000WH2X10&amp;linkCode=as2&amp;tag=danidolldes06-21&amp;linkId=5e049dc32f974304c20e04c605e1232a</a>"</p>
  
  <p>Which obviously doesn't exist.</p>
  
  <p>Hope i've explained this okay, sorry if it's hard to understand. I tried downloading a nofollow plugin to see if I could use that instead of doing it manually but still had the same outcome. I'm all out of ideas so any help would be much appreciated.<br>
  Thank you!</p>
