Component's Scope In A Component Block Is Incorrect

[chadhietala]

I believe the scoping of actions with curly components is incorrect on canary. The canary JSBin illustrates that when a component is yielded in a component block that scope is changed.

Thanks for reporting, this is definitely an issue with the recent removal of the controller and view template locals (done in #12286 around here).

Enabling those legacy flags does make this work properly (and is why the test suite passes). Will dig into it a bit more tonight...

Issue is with the @element_action keyword using scope.getLocal('controller').

Created failing test in: master...rwjblue:action-scoping. Working on fix tonight....

Submitted #12416 with a potential solution...
