Drawer under navigation next bug

Hey guys, just stumble upon a little bug with navigation-next and drawer, since i’ve updated to the last version of both package i have a z-index bug with drawers being under the navigation-next

the bug is also in the docs https://atlaskit.atlassian.com/examples/core/navigation-next/navigation-app clicking on the search icon

edit : it come from drawer component

after some research it seems that atlaskit-portal has a z-index zero containing a z-index 500 drawer
