Would fix #5406 but not like this :sad:

* Early win with working edit on shell

* Extend to logic to walls with tags

* Fixing inconsistencies in code. Tests not working on win

* Refactor addShell for consitency

* Clean up

* More clean up

* Add validation on both params

* Passing tests

* Prettier

* Change from test.skip to comment

* Clean up for review

* Add review suggestions and disable thickness validator

* A snapshot a day keeps the bugs away! 📷🐛 (OS: namespace-profile-ubuntu-8-cores)
