Aligning navigation button with left border

I am trying to create a side navigation button bar. When I click one of the buttons the icon’s position changes as there is a border in the div. How can we set the icons on the same vertical line when the border is in the clicked button?

In the picture below I wanted to have the "Test Manager" button in the same red line.

Here is the HTML for one of the buttons:

<a href="/testmanager">
<div class="is-active action-button">
<span class="material-symbols-outlined">content_paste</span>Test Manager
</div>
</a>

And CSS for the button:

.action-button {
  display: flex;
  flex-direction: column;
  justify-content: center;
  justify-items: center;
  text-align: center;
  color: #526069;
  height: 65px;
  width: 65px;
  font-size: 10px;
  font-weight: 600;
  line-height: 10px;
}

.action-button.is-active {
  background-color: white;
  border-left: 4px solid var(--branding-color);
}

.action-button:not(.is-active):hover {
  background-color: #E9F1FA;
}

>Solution :

One way would be something like this:

.action-button {
    /* other rules... */
    border-left: 4px solid transparent;
}
.action-button.active {
    border-left-color: var(--branding-color);
}
/* other rules... */

So now you will always have a border, hovering or emphasizing it would not change the layout.

But this has side effect: all text and icons will be aligned a little bit right (roughly 2px).
If you want them to be "truly" center, you may add another rule:

.action-button {
    border-right: 4px solid transparent;
}
