Ok, that makes perfect sense. To me dynamic scoping was very specifically a language mechanism. What you're describing is more of a framework mechanism and something that would be easier to make easy to understand.
Right, UI frameworks like Angular do dependency injection at the framework level because the underlying language doesn't have direct support for dynamic scope.
Sort of like how you can do object-oriented programming in C by making a struct of function pointers to create your own v-tables.
