Incorrect z-index for Popover on top of SubNavListItem

[zaviermiller]

Description

There is a bug with the new Marketplace search functionality where our navigation items that have a sub-list are appearing over the search popover.

Here is a screenshot:

The expected behavior of this page is that the popover and its elements appear on top of the list.

I have tracked the issue down to this line, and it appears that there has been a different PR that addressed a similar issue here.

Playing around in devtools shows the isolation fix from the PR does work here. Happy to open a PR to fix this!

Steps to reproduce

1. Visit https://github.com/marketplace?type=apps&copilot_app=true
2. Click the search bar and begin typing 'category'
3. Click on the category item that appears in the popover
4. Notice that the items from the popover are underneath the nav items with sub nav items.

Next steps would be to investigate the bug and figure out how much effort this would be

We'd definitely appreciate a PR if you have the time, but if not I can follow up with one! 😁
