[PATCH yew-widget-toolkit] fix #8057: correctly scroll on firefox with submenus

[Dominik Csapak <d.csapak@proxmox.com>]

There is a subtle difference in calculating the height of nested
grid containers: chrome uses the min-content height while firefox does
not. This means, on firefox, the navigation drawer would not have it's
intended size + scrollbars, but would clip the submenus since they would
shrink.

Fix this by giving the whole menu a container that can grow, and only
scroll the outer container.

This fixes an issue on PDM, where a bigger number of remotes would not
allow the users to scroll, but clip the list.

Fixes: f5bfd42 (widget: navigation drawer: make menu collapsing/expanding animated)
