Left Nav Issue

When using the left navigation component, the nav has inconsistent behavior in its relation to the rest of the layout.

To reproduce:

• open the left nav with the purple expand button, and watch the main content of the website shift to allow space for the expanded nav.

• Close the nav with the purple button

• Hover over the collapsed nav and it will expand

• Notice how the layout didn't shift this time, covering possible areas of the main content.

Desired: left nav does not expand over main content when hovered.

Please add more QA/Unit tests to these components. We got lucky we found this early as it would've blocked our team when we pulled it in.
