Bug - NavItem - Icons don't show if there are complex children

[rebeccaalpert]

Describe the problem
The NavItem lets you show an icon. However, this breaks if you pass in a child with a div.

How do you reproduce the problem?
If you give any NavItem a child that's wrapped in a div, the icon won't show: https://codesandbox.io/p/sandbox/agitated-babycat-rvrw7v?file=%2Findex.tsx%3A32%2C21&workspaceId=f5599198-6a68-44b3-85bd-1caed5609909

If you remove the div, the icon comes back.

Expected behavior
Icon should display consistently.

Is this issue blocking you?
