• 🔗 frontend-app-authoring PR

Description

This PR provides iframe reload optimizations for various xblock related actions. Added some improvements related to scrolling to the current xblock. Fixed behavior of the xblock action dropdown list.

Testing instructions

1. Open New Course Unit page.
2. When duplicating a block, a scroll to a new copy of the block occurs.
3. Delete, duplicate, drag xblock - a full iframe reboot should not occur.
4. Open a new xblock editor, save the changes - after returning to the course unit page, the page should scroll to the xblock for which the changes were made.

I'm happy with how this PR is looking, but I haven't tested it. I'm assuming @arbrandes will do the final review, but let me know if you want further review or testing from me. Thanks!
