[ios] Fix MagicStack UI Breakage when Toggling Feed off

This issue is result of the MagicStackCollectionView pulling in the
safe area insets when it never is within the safe area. For some reason,
when toggling the feed off, the MagicStackCollectionView receives
safe area insets, even though its final position is well outside of
the safe area. By setting UIContentInsetsReferenceNone to the
UICollectionViewCompositionalLayoutConfiguration, the items are not
inset to safe area insets.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure.

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.

If you found a bug, please file it at https://crbug.com/new.
