fix: Submenus Not Displaying Correctly in CodeSandbox

[break-stuff]

🐛 Bug Report

Submenus are not rendering correctly in a CodeSandbox environment

💻 Repro or Code Sample

🤔 Expected Behavior

😯 Current Behavior

When rendering submenus in a CodeSandbox environment, they are not hidden initially and overlap the menu contents rather than display to the right.

💁 Possible Solution

It looks like the slot is not being appropriately applied to the submenu. Setting a timeout to check for parent menus should fix the issue.

Thanks for the issue @break-stuff - looks like an issue with AnchoredRegion not being registered perhaps...we'll take a look. EDIT: I also see the slot not being applied here which is strange, we'll take a look there as well :).
