Cannot align contents of div to the left in Edge

We have a side menu where each list item contains an image and text which should be aligned to the left. It looks fine in Google Chrome, but IE and Edge render differently. I don't mind IE not working (I may try coming back to that at a later date) but Edge needs to work as expected.

I have tried using justify-content: flex-start on the <a> tag after changing it to display: flex which usually works but not in this situation.

<!-- begin snippet: js hide: false console: true babel: false --> <!-- language: lang-css -->

a {
  text-decoration: none;
}

ol,
ul {
  list-style: none;
}

#sidebar {
  width: 230px;
}

#sidebar ul {
  margin: 10px 0;
  padding: 0;
}

#sidebar li {
  margin: 0;
  padding: 0;
}

#sidebar ul a {
  display: inline-flex;
  align-items: center;
  text-align: left;
  white-space: pre-wrap;
  border: 1px solid grey;
  padding: 15px 20px;
  width: 155px;
  min-width: 155px;
}

#sidebar ul a img {
  margin: 0 15px 0 4px;
  padding: 0;
  height: 21px;
  width: 20px;
}

<!-- language: lang-html -->

<div id="sidebar">
  <ul>
    <li>
      <a href="#">
        <img src="https://i.imgur.com/UU5GJm7.png" >
        <span>Super Long Account Name</span>
      </a>
    </li>
  </ul>
</div>

Here's how the code renders in Chrome vs Edge:

Any help would be appreciated

I believe white-space: pre-wrap; is causing your issues

Try removing all instances of it (from selectors like the following):

#sidebar ul a {
  white-space: pre-wrap;
}

<!-- begin snippet: js hide: true console: true babel: null --> <!-- language: lang-css -->

a {
  text-decoration: none;
}

ol,
ul {
  list-style: none;
}

#sidebar {
  width: 230px;
}

#sidebar ul {
  margin: 10px 0;
  padding: 0;
}

#sidebar li {
  margin: 0;
  padding: 0;
}

#sidebar ul a {
  display: inline-flex;
  align-items: center;
  text-align: left;
  border: 1px solid grey;
  padding: 15px 20px;
  width: 155px;
  min-width: 155px;
}

#sidebar ul a img {
  margin: 0 15px 0 4px;
  padding: 0;
  height: 21px;
  width: 20px;
}

<!-- language: lang-html -->

<div id="sidebar">
  <ul>
    <li>
      <a href="#">
        <img src="https://i.imgur.com/UU5GJm7.png" >
        <span>Super Long Account Name</span>
      </a>
    </li>
  </ul>
</div>
